  1. User disconnects call

    in General Setup

    Posted

    Was that the complete email or you posted just the initial part?

     

    Extension to extension calling should not have any audio issues, unless the phone is remote and something in the remote network is blocking(NAT/firewall etc) some messages.

    If both phones are on the same network, just try to reset the phone and see if the problem goes away.

     

    That was the complete email yes, I'll post some more from the phone log the next time it occurs. It's hosted system so yes there it could be NAT/firewall but it's very intermittent and only seems to be effecting a particular extension.

    Hi all, i've been using the service of a 3rd party hosted VoIP and thought I'd have a try with by own PBX. As all our phones are Snom's the most logical choice was the Snom ONE pbx!

     

    Now all has been going fine but i've got a problem calling one of the extenstion, it rings, i can answer it but some times there is just no audio and the other phone just remains on "183 Session Progress" I then get an email sayiny snom PBX: User disconnects call:

    Any one got any pointers for me please? It always seems to be ext 1002 calling 1001 - I don't *think* i've had the issues 1001 calling 1002.
