After having both a soft phone on my laptop and soft phone on iPhone I thought that connecting a designed for VOIP phone would be very straightforward. I have had no luck in getting this phone to register with the device account I have setup. I am using the IP address of my server in order to rule out DNS.
As I'm running on Ubuntu 10.04 LTS then I'm stuck with asterisk 220.127.116.11-0ubuntu1.4 and using FreePBX 18.104.22.168
So FreePBX believes that there is only my soft phone registered. The SNOM 320 thinks it's registered as well but FreePBX doesn't agree.
Here's the really odd thing.
If I call my soft phone extension on the SNOM then it rings. I can hear voice from SOM->soft phone but not the other way round.
If I call the SNOM extension from the soft phone then I get an immediate Service Unavailable message.
So if it was a complete failure of communication then that would be one thing. But it isn't. It appears that some aspect of the SNOM 320 has registered but not all.
This does not make sense.
Can anyone please advice me on what the error is and how to resolve it?
