Lync 2010 interworking with 3rd PSTN Gateway RRS feed

  • Question

  • When making an outgoing call from Lync2010, the Lync Mediation server will send the INVITE with Request-URI as +862089185139@10.66.77.75 (10.66.77.75 is the PSTN gateway IP address configured in Topology Builder), the expected Request-URI by 3rd party PSTN gateway should be +862089185139@coe.net . Is there a powershell command or registry setting that can change Lync2010 mediation server behavior like this? The 3rd party will not accept the Request-URI as number@IP, and the outgoing call will fail

  • i don't think Lync would allow you request or header manipulation. You will need a session border controller foryou can try using coe.net for the gateway in topology builder (never tried it although) and use a host file to resolve coe.net into correct ip address

  • You have to convert the number, I think without the +

  • Jacky,

    Adminiuga is correct. You need SBC (Session Border Controller) to manipulate headers. Have you looked Audiocodes MSBG series Gateways (just resently released)? Another way is to use third party B2BUA (Back To Back User Agent), FreeSwitch for example. Although it will work, this solution is not officialy supported.

  • I am using the Audiocodes Mediant 1000 MSBG SBC for a site that needs this and it works perfectly.
