[bug] Voip over umts fails, not on WLAN

[qwertymc2]

Hi!
I have a Nokia 5630 XpressMusic with the latest firmware (version 11.020, so VoIP Rel 3.0) and SIP VoIP 3.x Settings v2.0. I have an asterisk PBX and I forwarded port 5060 UDP for SIP and 10.000 to 10.050 UDP for RTP.
This is the entry in sip.conf:
[general]
language=it
context=default
bindport=5060
externip=<ip>
localnet=<network>/<netmask>
[159]
type=friend
bindport=5060
context=phones-sip
host=dynamic
secret=<password>
disallow=all
allow=g729

While with the WLAN everything works flawlessly, with 3g network it registers succesfully but I cannot enable the service and so I cannot make and receive calls!
It isn't a provider issue (Wind, Italy) because if I use another SIP client it works flawlessly.

Please help me make it works, because voip is one of the main reasons because of I bought this phone!

Thank you!

I found the problem: I forgot to enable AWCDMA in Net Settings>Advanced VoIP settings>Voip Services>My service
