Handling multiple SIP peers RRS feed

  • Question

  •  

    Hi all,

     

    Need some clarification on how to handle multiple SIP peers with OCS 07:

     

    We have incoming PSTN calls routed to OCS SS'07 box through SIP gateway (sip peer1); and would like to transfer calls from OCS SS'07 hosted VXML app to another box over SIP (sip peer2).

     

    On the transfer, I can only specify the destination number and the SIP URI is constructed by OCS during the transfer. How to ensure it will always route traffic to sip peer2? When I specify a valid SIP URI, I get error from SS'07 saying it is not an accepted format.

     

    Thanks for your feedback.

    Ashish.

  • The transfer must go back to the originating Sip Peer.

     

    I see a few options:

    1. If your gateway supports it, you can specify a dial plan which is directed to the 2nd peer. This does not involve the PSTN.
    2. If your gateway supports it, you can direct calls to a specific DNIS to the 2nd peer. This is the regular PSTN transfer.
    3. Use a 2nd gateway and telephone number.

    It's really about tranfering in managed code but does explain some how the sip peer is chosen.

  • No, it does not.

     

    As you said, it is concerning managed code scenario. Unfortunately, In the VXML code I do not have a way to specify which "host.com" address to choose (as far as I know). and hence my original post requesting more detail on how can I do this....

  • Ouch...that's really a huge limitation.

     

    All the options you are suggesting will cause the port usage per call on the gateways to double. Clearly, not the best option.
