Nortel CS1000 along side Lync RRS feed

  • Question

  • I've seend a number of threads here but they're all towards dual forking.

    One of our clients can't have any more DID's added to their cs1000 and therefore we'd like to look at Lync to host these additional numbers.  If we install Lync can we set up a new set of internal extensions and allow the two systems to make internal calls to each other as in worker A calls worker B in the same office?

    I know Lync is able to have the PSTN gateway and we can configure routes for this.  It's more if the CS1000 is able to do it.

    Thanks

  • If you setup a SIP trunk between Lync and the CS1000 you should be able to allow users to call each other.

  • You can configure the CS1000 with direct SIP on mediation. 

    A SIP Trunk points from the Nortel PBX to the Lync mediation server using TCP over port 5060.

    Assign the Nortel PBX as gateway in topology.

    Have a look at this link:

  • What do you mean with no more DID's?

    Normal you can use 1-9XXX? in your PBX.

    If you configure a SIP Trunk to lync (it is possible), you will also need some numbers from the Nortel CS1000

  • You can also get the Nortel to pass the PSTN call from the CS1k as H323 and use a NET vx1200 to transcode onto the lync mediation as SIP.
