Asterisk version: 1.2.8
I checked and re-checked config files on the asterisk server, they’re OK!
I checked the Snom get its IP-adres from the dhcp server, that’s OK!
I sniffed the communication between the Snom and the Asterisk server.
I see the Snom send a SIP message to the Asterisk server to register.
Then the Asterisk server try to connect to the Snom on a certain port but failed because port was probable not opened. An ICMP message with host unreachable is the response.
It is possible to ping the Snom from the Asterisk server !
What is possibly missing in the configuration of the Snom 320 ?
Could the image on the Snom be corrupted ?
