Hi All,
I'm trying to set up a remote phone via the SIP Proxy Mgr. The SPM tunnel seems to be established ok, but can't get the phone to register (408 - timeout).
3CX softphone works in tunnel mode form the location, but not via the SPM.
I can see the registration attempt in the SPM Logviewer and in the server tunnel logs as well:
This is where it gets odd: I suspected our office firewall blocking something, so I did a trace. It seems the PBX is attempting to send UDP:5080 packets to the IP address of the computer where the SPM is installed. This is in fact blocked on our firewall, but even if it wasn't, that IP is not routable (private class C).
It seems to me that the PBX is not using the tunnel to respond to the registration request (I can see those outbound attempts every time I try to register an extension via the SPM).
I'm sure it's some simple configuration mistake on my part, but I can't seem to figure it out.
Any help and/or pointers would be greatly appreciated!!
Thx&Rgds - Marcus.
