    Hello everyone!

    I am trying to deploy UM with Office 365 Hosted Exchange. We are using one Lync 2013 Standard Edition FE and have deployed one edge server. We have set up our firewall to host the Reverse Proxy.

    We do not use wildcard certs. External DNS resolves the _sipfederation and sip._tls SRV records to the external face of the edge server. The edge server functions as it should for remote users and mobility.

    I have tried to follow these instructions to the letter three times over to no avail.

    http://y0av.me/2014/01/07/lyncum365/

    Neither Snooper or Event Viewer show any particular issue, though when I try to dial out to voice mail I will get one to two rings and then 5 seconds of silence a fast busy, and finally "Call Unsuccessful".

    When checking the firewall logs I notice a seemingly random 10.x.x.x address being sent to the firewall by the external leg of the edge server. Wireshark captures it as STUN packets on port 3478 being sent to port 3478. These are being dropped by our firewall. I believe them to be RTP packets but I do not know if this is normal behavior. Has anyone any ideas?

    Confirm you have correct static routes on your Edge's internal nic to all Lync Server and Lync Client subnets. Have you restarted the Edge server? If NATing the External interface of the Edge server make sure the NAT is bidirectional.

    Did you run Snooper on the Edge server? Running on the Front End doesn't give much details for Hosted voice mail.

    My mistake. Here is the snooper result.

    Interestingly enough, I enabled NAT on the A/V Edge service in Topology Builder and entered the NAT enabled public IP address, exported the configuration over to the edge, rebooted and all is well.

    It very well could have been just simply rebooting the server. Thanks for your thoughts and ideas.
