I'm trying to set up a SIP line on a snom 300 phone but have hit a wall.
"Identity1" on the phone has been set up and is working fine as an extension on our PBX (Asterisk). "Identity 2" has been set up to communicate directly with Gamma (the SIP line provider) rather than going through the PBX.
If I go to System Information on the phone I can see that Identity 2 has been given the "ok" suggesting that it has registered ok, but if I try and ring the number it doesn't connect (I either get a message saying the number is not available, or just silence after I've dialled, depending what sort of phone I dial from).
I'm sure I'm missing something very simple here.. anyone have any ideas?
