sudo Posted September 8, 2012 Report Share Posted September 8, 2012 I have a snomONE box setup with a pbxnsip license to support 3rd party devices. In this case Polycom IP 331. I have setup a domain. Phones register and are calling in and out. All good there... BUT - When you call voicemail, either by the message soft button, or by calling the extension number/starcode, the phone acts like it connects, but then it hangs, just sitting on dead air, never connecting. I then connected a Polycom IP 331 in my VoIP lab, connected it to the same domain and it connects with out delay, asking me for my pin and playing my messages What in the world could be causing this? Thanks in advance! Sudo Quote Link to comment Share on other sites More sharing options...
Vodia PBX Posted September 8, 2012 Report Share Posted September 8, 2012 Is this really related to voicemail? What if you use other services, e.g. call the auto attendant? It sounds to me like a problem more related to the phone. For example, one phone could be in the LAN, the other one in the WAN. Quote Link to comment Share on other sites More sharing options...
sudo Posted September 10, 2012 Author Report Share Posted September 10, 2012 Looking at the pcap: I get a "405: method not allowed" response from the client side. I would guess that it could be a firewall blocking this traffic, but i think that this all runs off port 5060 and 80. I had them try dialing the AA and it rang as busy. Again I can dial the AA from my VoIP lab connected to the same domain and get through. What could be blocking this? Any suggestions or info is greatly appreciated.

sudo Posted September 10, 2012 Author Report Share Posted September 10, 2012 Solved. The issue was their firewall. It was set to - "SIP Deep Packet inspection". Similar to SIP ALG. Turned it off and the phones can connect to vm/AA. Silly mistake - thought Id post the solution to any for anyone else who might experience this issue. Thanks to those who posted!

Vodia PBX Posted September 10, 2012 Report Share Posted September 10, 2012 Thanks for the update. The motto "what I dont understand cant be allowed" seems to prevail on firewalls... Quote Link to comment Share on other sites More sharing options...
