We do not have these problems with the snom 190. It is probably a 
combination of your settings in sip.conf (maxexpirey & defaultexpirey) 
and the 'Proposed Expiry' of the snom (defaults to 1 hour, 
user_expiry1: 3600)

Do you have the original snom headset? Our snom headsets do not have 
any logo on it. One of the tech people from Snom told me they have a 
built-in amplifier for the microphone. Did you connect the headset to 
the special RJ connector? We also changed the volumes:
headset_device&: headset_rj
vol_headset_mic!: 8
vol_headset!: 15

In the beginning we had big problems with the headset because of an 
annoying  buzzing sound. With help of Snom we figured out that a 
shielded UTP cable, connected to a grounded switch (or PC) solved this 
problem.

Yes, could be better, but not really annoying.
