NORTEL / AVAYA PHONES and LYNC / OCS - Are they friends or not? RRS feed

  • Question

  • Just wondering if anyone was able to connect any NORTEL (now AVAYA) IP phone to LYNC or OCS?

    We are NORTEL workshop at the moment (because of CS1000 IP PBX) and don't have any OCS/LYNC phones but we recently deployed LYNC 2010 and I want to know if it will be possible to connect somehow NORTEL / AVAYA IP phone to LYNC 2010 front end or mediation server.

    If you have any insight please let me know, thanks!

  • You cannot connect regular Nortel / Avaya Phones directly to a Lync server. You might be able to register them on a supported gateway (like AudioCodes or Dialogic) and configure routing integration on the Lync server, but they won't talk directly with the Lync server. I wouldn't recommend this setup, you would lose a lot of features compared to the similar priced Lync common area phones.

  • It's also possible to use third party software (like NET's SmartSIP) if the phones support a SIP-only mode. That way you get call control/presence as well. The caveat is that SmartSIP is currently supported on OCS R2 mediation servers, so you'd lose media bypass and mediation server pools.

  • Hi,

      Actually I can connect CS1K phoneset to Lync 2010 by Direct SIP. Although CS1K is not certified by Microsoft for Lync 2010 Direct SIP, I did setup lab with CS1KE Rel 6.0 Direct SIP with Lync 2010 . The lync phone can call the CS1K IP phone and CS1K IP phone can call lync phone. They work perfectly.

  • Hi Jacky,

    Thanks for you reply. Can you please confirm whether you were able to connect AVAYA desktop IP Phone like model 1120E to Lync 2010 server, or you were able actully connect Lync with CS1000 PBX using direct SIP (or whatever it is called) for two-way calling between LYNC and PBX phones?

    We are trying to connect Lync to PBX for 2-way calling for almost a year by now and have no luck. One of the challenges we have is that our IP PBX is not managed by us (external vendor is in charge) so I don't know wheter we are doing something wrong or this is not even compatible.

    If you can clarify that would be great!

    Thanks!

  • Hi Alexgarin,

    Based on Jacky Fan's post, he connected the Nortel PBX with Lync using a Direct SIP link, so the phone talks to the Nortel PBX and the Nortel PBX talks to Lync. The Phone is not registered directly. I've done such integrations a few times with Nortel CS1000 systems.

    For your situation I'm 100% sure it is possible to let your PBX talk to Lync, either directly using SIP or by an intermediate gateway. This gateway will be able to talk to Lync and your PBX in a supported way and has to be scaled correctly for calls and connection type.

    I would recommend you to talk to a partner with specialised knowledge in integrations (Like me & my employer ;-)) regarding your question. Based on the information you would provide (Like PBX brand, model, software versions, number of users), partners like us could give you an overview of your options and guide you through the entire process of the integration.
