[Freeswitch-users] Aastra phone registration lost

Based on your input, I kept those settings :
sip registration period: 3600
sip registration renewal timer: 3000

The phone registers to FS every 10 minutes. However, any other
registration period does not work like it should. It's obvious to me
that the phone ignores the expires parameter given in the Contact HF
and actually uses what I believe to be its default registation period
(3600 sec).

I tried to insert an Expires HF to the 200 REGISTER response sent back
from FS, and then the phone re-registers based on the time given in
this Header Field. It therefore seems to me that the phone is buggy,
even though adjusting the two parameters like you suggested it
perfectly solves the registration issue.

Thanks again,
