I have an SNOM 300 that I use on voipfone. I set up a call just now,
with a radio near the phone at one end (to provide continuous
"conference" audio), and I muted the other end (to inhibit all audio).
There was no break in the connection for over 20 minutes, after which
time I manually terminated the call.

On your SNOM 300, I wonder if you have an inappropriate setting for the
"Presence Inactivity Timeout" (under Preferences > Privacy Settings)?
