Re: [Siproxd-users] siproxd-0.7.0-4577 and Nokia N95 prob

[sp4rc <sam...@gm...>]

Just for others who maybe struggling with the Nokia N95 VoIP Client and
siproxd.

As you may derive from my TCP dump its not possible to disable the
mobiles STUN functionality and that's the reason it fails in registering
with the voice service provider (sipgate in this case). Simply rejecting
(!= DROP) 3478/udp (STUN) made the trick, this took me about 2 weeks to
figure it out... yes I am new to SIP/SDP/RTP :-) 

This is what my sipgate.de configuration for the Nokia device looks
like:

- Profilename: sipgate-profile
- Dienstprofile: IETF
- Std-Zug-Pkt: your AP
- Öff. Benutzername: sip:you...@si... 
- Komprimierung verwenden: nein
- Anmeldung: Bei Bedarf... or whatever
- Sicherheitsmech. verwenden: Nein

- Proxyserver
  - Proxyserveradr: sip:192.168.1.1
  - Gebiet: sipgate.de
  - Benutzername: your_user_id
  - Password: your_pass
  - Loose Routing erlauben: ja
  - Transporttyp: UDP
  - Port: 5060

- Anmeldeserver
  - Anmeldeserveradr: sip:sipgate.de
  - Gebiet: sipgate.de
  - Benutzername: your_user_id
  - Password: your_pass
  - Transporttyp: UDP
  - Port: 5060

Have fun...
