Lync server PSTN connective problems RRS feed

  • Question

  • I setup a Lync (Standard Edition ) lab environment, now I have meet some PSTN connective problems confused to me:

    1. Do I need to deploy the Edge Server on the Standard Edition Lync lab environment? Another words, can I connect to ITSP by using Lync FE SE only?

    2. I have a ATA (Cisco SPA3000) device, can I use it as a PSTN gateway instead the normal PSTN gateway qualified for Lync Server ?

    3. I have a ITSP:114.80.200.36, and I have publish it as a PSTN gateway in the Topology Builder. How can I know the Mediation server is communicate with ITSP normally? Are there any log files record this? Because I can see the 114.80.200.36's Status is N/A on Lync Server Control Pannel.

  • 1. Edge is for federation and remote connectivity, it is not required or used for an ITSP. An ITTP will connect to a mediation server (or a gateway), mediation can be co located on an SE so yes you can connect and ITSP to an SE. However it would be more common to have a dedicated mediation server.

    2. If the ATA can provide G711 SIP on one side this will work yes.

    3. check out lync logger and snooper - just do a search for them you will find lots of good blog posts.

    thanks

    No, you need the Edge only, if you want to conect external client or use federation.

    2. I have a ATA (Cisco SPA3000) device, can I use it as a PSTN gateway instead the normal PSTN gateway qualified for Lync Server ?

    I don't know your ATA, I think it will not work but you can try to connect, if the GW supports the requirements for Lync.

    3. I have a ITSP:114.80.200.36, and I have publish it as a PSTN gateway in the Topology Builder. How can I know the Mediation server is communicate with ITSP normally? Are there any log files record this? Because I can see the 114.80.200.36's Status is N/A on Lync Server Control Pannel.

    The mediationserver connection to ITSP doesn't support NAT, so you have to use a SBC or connect the ITSP direct to a Networkcard of your FE with less security ofcourse. To trace the sip communication, you can use the ocslogger too in the Lync program folder and trace Mediationserver, Sipstack,S4 to see what goes wrong
