asterisk users - Sep 2006 - Off-hooking Snom hanset doesn't answer incoming call

Hi,

Any advice on this one ?

Sometimes off-hooking a Snom 320 handset doesn't answer a multi-extension
call : phones keep ringing while handset remains silent.
This occurs for 1 to 5% of incoming calls.

The setup is bristuffed 1.2.10 Asterisk with Junghanns QuadBRI and
6.2.xfirmware Snom 320.
Every call comes from ISDN network.

Thanks in advance

If the phone keeps ringing I guess it is a bug in the phone. I had a 
snom which had a broken switch (which detects off/on hook).
