G.711 RRS feed

  • Question

  • I've read that OCS2010 (wave14) natively should support G.711.
    This should give support for all the VoIP phones out there or not??

    I'm thinking of reusing phones from other systems like Cisco/Nortel/Avaya etc.
    Would that be possible and if not, why support G.711?? Is the mediationserver going to be depreciated in the future??

    TIA

  • Hi Kent,

    The question your asking isnt really about codecs. If you wanted to use G.711 right now with OCS R2 you could as OCS and OC already support this. As for depreciating the mediation server, this is an integral part of the overall OCS solution that does a lot more than transcoding. Some gateway vendors have already began to build the mediation server role direclty into the gateway. At this time thats all I can say about that in a public forum.

    So reusing phones has a number of challenges and is currently not support by OCS but there are other products out there from thrid party vendors that will allow it. SmartSIP from Evangelize is one that comes to mind. The codec is not the only issue when it come to reusing phones. The other factors include the phone firmware support of SRTP and TLS and the ability to authenticate to OCS. So when you put all those things together unless there is a specific firmware build to support OCS most phones  cant register with OCS. SNOM and Polycom have built OCS specific firmware that allows them to register to OCS as examples.

    Cheers

  • Thank you for the reply.
    I understand that endpoints have to authenticate into OCSR2 as it is currently working. I guess I'm just hoping for better support for less intelligent phones what are much cheaper (standalone). F.ex. is Polycom's CX700 IP Phone just as expensive as buying a hole desktop computer with headset.
    The number of phones for OCS on the market that I can find is very limited, and has been the same for years now unlike what I expected back in 2007.

  • Totally agree with you Kent. Look for more news on this subject in the coming months.

  • Frankly, I don't understand why Microsoft is so stubborn on the endpoints line. Even the new OAK (Polycom CX300) is USB device. So, if we have to place a phone in the kitchen block, a $199 phone actually costs $750 (because we have to add PC to the phone (smile)), plus the troubles of keeping the workers from over-frying the chicken while jerking on Internet.

  • Hi Drago,

    Not sure if its a question of stubborn but more of a maturing product along with maturing relationships with product partners. Pretty sure if you look back at Cisco's product development path its taken quite a long time to get where they are now with endpoint choice. Although Mcirosoft is on an accelerated path its not something that happens over night.

    Cheers

  • Well, it would be very interesting to hear/see what MS's plans on this subject. The last +2 years have shown that other manufactures aren't just providing complex endpoints to make MS happy. MS has to lower the requirements for endpoints or start making 100 different endpoints themselve.
    There are many situations where you don't want to place a PC, or its simply not supported.

    What about companies that want to run OCS exclusively?? They're stuck with endpoints at a very high price. MS can't be happy about that at all.........
    How long are we stuck with the "old school" PBX's??        Wave14 help us!!!

  • Hi Kent,

    Talk to you local MS resources on wave 14 voice briefs.

  • Yeah, I'm part of the local MS PET team (as partner). Next meeting in about a month. I will try to pull some answers on this topic. It's just annoying me right now because I have a customer who wants OCS without any PBX integration (eg. replace all PBX's with OCS) but the endpoint price is just killing the total project price.
    So I read that wave 14 would support G.711 natively, and wondering what that mean. It could be anything hense the question here.

  • Let's face it - up until last year (where on VoiceCon MS announced "Getting out of hardware business"), all endpoints - MOC, CX100; 200, and 700 were developed by Microsoft and OEMed to Poly and LG-Nortel. There was never a "partnership"... There is no partnership now either - Poly "holds" the production line and we have not seen (or heard) anything else on the works. We all know the reason - RTAudio licensing. As I mentioned before, a successful deployment should not (nor can) relay on "smart" codec to solve sloppy networking.

  • Kent,

    OCS (2007 and R2) does have native support for G.711.

    88% of our endpoints are Snom300 (standalone phone with native registration against OCS.) I intentionally did not mention Snom in the beginning of this conversation because Snom is not OCS certified. We are happily using it 8 months already… This includes LAN users and remote workers as well.

    Drago


    Ah, Norm. On the next breefing, will you please ask WHEN the concept of USB pairing will be an option, not THE ONLY option?

  • I dont think RTAudio licensing is the only reason here as a vendor can use G711 or G722 if they really want to, as SNOM have done. Tanberg, Polycom and others have licensed RTAudio so the issues goes way beyond just licensing. Like I said earlier, these things take time and customer opions certainly count . The best thing you guys can do is talk with local MS resources and let them know whats holding you back from beign successful so they can pass it on to the product groups to make improvements.

  • Dont be confused by voicing an opion in a public forum and being able to give direct feedback from a customer backed perspective. One holds much more weight than another even though MS employees such as myself monitor these forums. Dont get me wrong forums are great for talking about these issues but direct feedback is critical to your and MS success moving forward.

  • Hi Kent

    Same comment as Chris here...Look at an NET gateway with smartSIP this will allow you to use almost any SIP endpoint with OCS - this way you wont need a mediation server either (VX1200 have it built in as well as AD)

    Cheers,
