I have been toying with the N95 for about a week and the nokia SIP client might be slightly not RFC compliant according to my findings. I am trying to register with a SIP provider here in Ireland and it always fails to register with a simple message going : Registration Failed.
The problem seems to be lying in the Contact header, it seems that the phone might be expecting it to be identical to what it sends which clearly isn't SIP standard.
So that brings me to the following questions :
- Is anyone aware of this issue ?
- Is there a firmware lined up ?
