IBM To Run VoIP On Linux 198

hrhsoleil writes "Johnny Barnes, IBM's vice president of global IT solutions and standards, told attendees at a TechTarget conference this week that his company plans to migrate at least 80% of its more than 300,000 employees to voice over IP by 2008. The project will replace approximately 900 PBXs around the world with regional IP installations. IBM's server-based IP telephony platform is going to run on Linux."

    So. . . IBM is converting its employees to VoIP

    Sounds interesting, I hope this is done in a humane way.

      IBM makes its money from selling server equipment. They arent taking sides in the holy war, they are just using Linux as a vehicle to drive their hardware sales. Why not use a vehicle in which other people are doing most of the work for you?

      IBM and Linux - its just a business decision.

    How is IBM going to handle irate state-owned telecos who are suddenly deprived of IBM monies? Will they grease the wheels with payola (less than they were paying for phone calls) or will Big Blue just tell them to go take a hike? Interested businesses want to know... is it safe for anyone to try and get around the monopolies now, or is it just safe for IBM?

    Hell, here in the good old USA the "regulators" are already clamoring over the loss of all that free money that they've been siphoning out of our checkbooks. I can't imagine a state OWNED monopoly from doing any differently...

      IBM is replacing in-house PBX systems. The telcos will still get their money from PSTN and data trunks.

      IBM is using linux for VoIP. This has nothing to do with phone companys.

      • by Anonymous Coward
        It does. Presumably phone company x gets granted a monopoly on phonelines on condition that it provides them to anyone who wants one - the effect is some (unprofitable e.g. middle-of-nowhere) lines are subsidsed by the majority profitable ones. If a significant proportion of the profitable lines are abandoned in favour of voip, the teleco gets upset.
        Alternatively the teleco was really a stealth tax, and the gov doesn't want it side-stepped.

          But you cant replace a phone line with a protocol to no-where.
          You still need a PSTN connection if you plan on talking to other peoples phones.

          I cant see IBM cutting their phones off from the rest of the world, and no longer accepting any phone calls. Why do you think this is what they will do? that would be very stupid, for any company do give up their phone presence.

            The poster obviously doesn't understand what enterprise VOIP is all about. Actually, there are two different things going on, and people often confuse the two.

            1. VOIP - send voice protocols over IP. So, instead of paying for a tie line between two of my campus locations, I route voice from my PBX across my wide area data circuits to my other location and terminate onto another PBX. This is all about

          Yes, I know this. Aparneltly you and the parent poster (and most of the replys Ive read) dont understand the difference between a PBX and the PSTN.

          Think of a PBX as a network switch, or a NAT device.
          Then think of the PSTN as the Internet.

          (Ok horid comparisons but go with me on this for a sec)

          Now, basically what you are saying is "If you replace your home switch/NAT device, with another one, wont your ISP get pissed off that you are by-passing them for internet access?"
          Now you can see, you still would need an ISP to get to the internet, and having a number of computers connected to a switch has nothing what so ever to do with the internet, even thou the possibility of being connected to the internet is there.

          If you have a PBX, you still need to conect to the PSTN if you plan on making calls to any other phones on the PSTnetwork.

          I can't see IBM chaning from older PBX to newer VoIP technology, and then for no reason what so ever disconnecting from the PSTN and not paying the phone company. Noone would be able to call IBM, and they couldnt call out!

          Now a little network leason.

          I'm sure you have heard of what a T1 is. A T1 is a type of service (NOT a type of line/connection) which most people dont make that distinction.
          The physical line is called a DS1. A DS1 is 24 B channels (Each B channel is 64k/sec of bandwidth)
          A DS0 is one channel (ISDN has one or two of these), a DS1 is 24, and a DS3 is 720 B's (I think, a DS3 is 30 DS1's)
          So, a DS1 is the line. When you use all those B channels as one data line, the DS1 is called a T1. But a T1 is not the only option.
          You can also keep those 24 channels seperate, and in this case the DS1 is called a PRI. With this setup, you generally turn up one or more of these 24 channels each as its own phoneline, so you can get 24 phonelines.
          Due to switching, this isnt exactly acurate. You either set the PRI to have 24 channels of 56k each, or 23 channels of 64k. The extra space is used for signaling. If you are doing voice, or analog dialup for an isp, you can go with 24 chanels of 56k.. the extra 8k is switching.
          Or you can just reserve one whole channel for switching, and use the remaining 23 at their full 64k and do all of voice, analog dialup, and additionally ISDN dialup. For voice, one generally uses 24 chans at 56k, as a phone line wont use much more than 8-16k of bandwidth anyways, and specifically for a phone system, modems dont come into play.

          Now back to why I typed all that.

          If you have say 3 offices, one being the main office. You get a number of PRI's into the building for your PSTN connection, each PRI giving you 24 phone lines.
          Then you get a T1 connection from that office to the other two.
          The PBX is able to route calls over the T1's between offices, and then route however is needed to get to the PRIs when someone needs to use an external line.

          PBX's ususally use their own wierd data format, so an entire T1 is wasted on this one function. (IP is not running over it)

          With VoIP, they can either use existing point-to-point IP links (Im sure IBM has faster than a single T1 internal links between offices already) and just use those. They can also take that T1 they had before and convert it to IP, or just get rid of it if they have much faster bandwidth already (IE a T3 or better)

          The links between offices are ALREADY being provided by the phone companys.
          It really depends if they continue to use their dedicated phone links with IP, or if they cancel those lines to use existing backbone connections they already have for IP. That will be the ONLY change the phone company would see.

          VoIP just adds more
          • Shoot, also forgot to note that IBM had a global network before they sold it off to AT&T, even has its own Class A network. So they probably already route all their calls internally over this network. They also have their own 7 digit internal phone numbers. I have a feeling that their internal phone and network system is more advanced than most countries, they (we) have been doing networking for a really long time.

      1. There aren't many state-owned phone companies left in the world due to "Structural Adjustment Programs"
      2. Where there are State-Owned Telcos, IBM will probably be paying them for internet connectivity
      3. This is really just a sign to sell stock in companies that produce PBX equipment but not VoIP servers/handsets

    • Well making Internal changes should do nothing but Demonstrate Prices are far too high for Voice services... When they can impliment something that does the job for less money...

      After all Not much can Stop IBM unless they start to see services on the VOIP system they are putting in.


    • The Telcos own all the fiber in the ground anyways. Just instead of charging them for voice it will all be Data. But you bring up a good point. I wouldn't be surprise if telcos start lobbying for tarrifs on VoIP. like they did when the interenet started getting popular.
    • I believe that if the company uses it for internal stuff (no external calls) then different laws apply. Yes, it could still be illegal, but company2company comunications are a different beast than public VoIP. IBM has it's own 100% private network for all corporate stuff, there is no chance of communications beign intercepted by third parties.

    • You're either quite stupid, or make horrible jokes. VoIP interfaces to the regular telephone system and is transparent to the phone handset, giving you a ten-digit number like you're used to. And as to the economics of it, I think it's good. It's not going to hurt the telcos any, they gouge everyone else enough. Besides, it might not even change the services they buy anyway. I'd bet that IBM has fast fiber trunks to most of the larger facilities which just digitize everything anyway, and they're probably p

    • I think that IP will be the next "Phone Number". Someday, someone is going to offer your cable, phone, and HSI all on one connection. Or more likely the content is going to be merged to being more "online". Voice and the internet are starting to take off, how long until we get on demand video from sat or cable?
  • This may be a dumb question but....

    As more and more of our traditional communications mediums move onto IP, won't it be easier for crackers to comproomise these things?

    For example, it may be difficult for a cracker to get his hands on a pbx let alone a working environment to do his "R & D" in. But as eveything moves to using really common standards, it gets pretty easy to test this stuff in his mom's basement or whatever...

    "Hello, this is the operator." Is it?

    • Good point, and not to throw in the Lin/win debate, but I think that they more than likely considered this and it is why they have chosen an open source solution. They can author, patch, admin and TRUST their own work, on their own system.

      I wonder also with the drop of the PBX's will IBM become or position itself to become a baby bell in it's own right. Just a thought.

    • Interesting point. I wonder if any research has been done on this topic.
    • In general I think that script-kiddy type hackers would have more of a chance at getting the data. However, one would expect any important communications to happen within an encrypted channel.

      One thing to note is that moving internal networks (phone, computer, etc) over to IP is not the same as putting all of these things onto the Internet.

      At the scale IBM is talking about here; 900 PBXs worldwide, don't you think it's already closely mated to their IP network? How do you suppose they manage all those phones and voicemail? Who makes those PBXs and how well are they maintained? 10 year old firmware revisions and crappy 4 character universal passwords remotely accessible through unencrypted terminal emulation, probably. Half a dozen different vendors involved too, most likely.

      Odds are the system is already vulnerable to anyone with marginal PBX technical expertise. At least now they'll have a very contemporary platform that is up-to-date and easy to keep that way.

      Look, PBXs are the ultimate evolution of manual switchboards. It's legacy stuff and it needs to die. Moving low quality noise around does not justify proprietary hardware.
    • As more and more of our traditional communications mediums move onto IP, won't it be easier for crackers to comproomise these things?

      Well, yeah, it'll just be easier to find VoIP servers.

      In general, though, it probably will not be as bad as you're thinking. VoIP is not a new technology, and the security issues with it are well understood.

      That's why many of the protocols have security measures built in. In addition, because it's IP, you can use IPSec and other protocols for IP security.

      • Well cost savings is really the big bang of VoIP. If your company is rolling in the dough so much that they don't care what they spend I can't see how you get them to pay attention.

    Since they are extremely decentralized, this is REALLY a gamble for them. Imaging half of IBM "winking out" when their PBX network dies. I'm happy that they are brave enough to do this, but I worry for Linux's reputation if it becomes a boondogle.
    • Just because they're dropping PBXs doesn't mean they're dropping redundancy or failover. If one of the call centers goes down (very rare if you have redundant providers, power), switcheroo to the other one - send staff over to the other location.

    Are the voip calls going to be encrypted?

    Vonage may not encrypt calls, but at least on the IBM end, until it reaches the demarc line, they should stand up and do the right thing and encrypt all their voip calls.

    Perhaps this will be the kick in the pants that everyone who is in love with voip needs.

    Transmitting voip calls over the internet is absolutely nuts without encryption. Forget about tapping a phone line with recording equipment. Now all you need is a minimal size hard drive, and standard apps available on all platforms to tap into and record "telephone" conversations.

    Don't forget that because wireless telephones aren't considered "secure" by courts, it doesn't require a search warrant, or line tap warrant to record the conversations. By using unencrypted voip, the bar is being lowered to no requirement for a search/line warrant for intercepting all voip phone conversations. And it looks like everyone, including the phone companies are migrating toward voip.

    There have been slashdot stories raising big stinks about echelon, about tia, and about the fight over the strength of encryption allowed as exports, encryption classified as munitions, storing encryption keys with the government/clipper, and big stinks have been raised about each of these stories. Yet I've only heard of one company that I can't recall the name of right now that is offering encrypted calls, and they said that if the government needs access, they can turn over the conversation, as they are the midpoint on the encryption, and all the packets are cached on their servers anyway...

          Well, you can buy IP capable phones from a variety of sources. I'm sure that at least some of them are capable of interfacing with any call manager using QSIG and SIP. In fact, I'm almost positive that the Cisco phones don't care what call manager they interface with as long as the signaling comes in correctly. Software phones are convenient for those who travel or work remotely (at home for example) but they are not particularly conv

        • you get the T1 card and a 24 port FXS channel bank. Total cost - less than 4 digits

          Then you can set the line coding on a per port basis to handle normal pots phones, some vendors custom handsets, etc.

          you can get the quad span card and get 96 analog handsets on a single PCI board. Put multiple pci boards in a box and your port density is atrocious. multiple asterisk boxes can switch channels over ethernet, so you can get into multi-hundreds of ports very easily and quickly.

    This is just a ruse (shhhhh...) by IBM to bankrupt SCO. If SCO pays IBM to not use Linux by the gazillion truckloads, SCO goes bankrupt and Darl, being deprived of his crack allowance checks into the detox unit.

    I work for Alcatel Belgium (I work on the SMC 5735 RADIUS Proxy [alcatel.com], a part of the 5020 SoftSwitch), and I can assure you that quite a number of products run on Linux, for example our OmniPCXOffice [alcatel.com] products. And you might find even more in the future (can't comment on that).

    Other companies provide Linux based solutions too. And why not ? It's just an operating system. The fact that the Telecom companies are choosing Linux just proves that Linux is very stable. The actual fact that it's free has nothing to do with it (the cost for a license would be an extremely small part in the TCO).

    And no, it can't be downloaded for free, just because it's Linux. That the first question my friends alwasy ask. Most of the software is propriety, and often written for special hardware. And also extremly expensive ofcourse, otherwise who would pay for all those hundreds of engineers that are developing them ?

    VoIP is NOT the same thing as IP Telephony, yet folks here seem to use it interchangeably. Is IBM doing one, the other, or both? It's impossible to tell from the post. Voice over IP is simply packetizing voice somewhere within the network, mostly likely between PBX's while the handsets stay traditional. IP Telephony means even the handsets talk IP and can packetize the voice. In other words, everything is IP. Please know the difference.
    • Is IBM doing one, the other, or both? It's impossible to tell from the post.

      From reading the article it is clear they are doing IP Telephony. IBM has been doing VOIP for years, just like every other Fortune 1000 has. But replacing 900 PBX with VOIP really means IP Telephony, but the guy writing the article doesn't know the difference so he calls it VOIP.
