    This is pretty odd.  For some reason, out of all the people in the office I am not able to call long distance numbers and hear what the people on the other end are saying.  If I use someone else's phone, the call works fine.  Sometimes when calling from mine I will hear them say hello, then after that they can hear everything I'm saying but I am not able to hear anything they are saying.  I don't know how I should troubleshoot this.  Does anyone have a suggestion?

    How are you integrating with Telepony?

    Gateway, SIP Trunk or with PBX?

    Most probably you will have Firewall issues, you have a one way audio stream!

    We have a Dialogic DMG2030 media gateway connected to an AdTran TA908G2.  Why would it be a firewall problem if other people can call, but I can't?  Seems like traffic is flowing proper to everyone else...  That's what confuses me about this.  If everyone was having the problem I'd definitely suspect configuration, but since it's just my phone I have no idea.

    Another user has reported this problem.  He says that it is hit and miss.  Some long distance people he can call and have 2 way audio, others can only hear him.

    funny audio issues are almost always firewall issues.

    We don't run a software firewall, and I wouldn't think SIP traffic would even be touching our Fortigate.  What firewall would be blocking it?

    This is still happening.  I echo my previous question since I haven't received a reply.  Any other suggestions welcome.  Lync is running on a 2008 R2 VM if that makes any difference.
