I'm getting the same error but on my E65.
"Internet Telephone Service Not Availible" but I'm able to receive calls, just not able to place them.
Does your provider require an outbound proxy? Mine apparently does (it's a local provider).
ie. Here are some of the settings:
My VOIP Provider has the following requirements for clients:
Username: 00000
Domain: aci.on.ca
Auth Username: 0000@aci.on.ca
Proxy: aci.on.ca
Domain: aci.on.ca
Auth Realm: aci.on.ca
Outbound Proxy: sip.aci.on.ca
Outbound Proxy Port: 5060
Use Outbound Proxy: Yes
Now on the handset I've setup the following:
Under Settings -> Connection -> SIP Settings
Service Profile: IETF
Default Access Point: My AP
Public Username: 00000@aci.on.ca (SIP: prefix auto included and 00000 replaced with my username)
Use Compression: No
Registration: Always On
Use Security: No
In the Proxy Server Menu:
Proxy Server: sip.aci.on.ca (this allows to connect but there is no mention of outbound or regular proxy, or where I can select 'use outbound proxy') (if I remove the 'sip.' I am unable to register with my provider)
Realm: aci.on.ca
Username: 00000
Password: ***************
Allow Loose Routing: Yes
Transport Type: Auto
Port: 5060
Under the Registrar Server Menu:
Registrar Serv. Addr: aci.on.ca (makes no difference if I make the address exactly the same as the proxy menu, I still cannot send outbound)
Realm: aci.on.ca
Username: 00000
Password: ***************
Transport Type: Auto
Port: 5060
----------------------------------
I also sent a request to Nokia and my provider. Hopefully a solution can be found. It'll definitely increase the value of our handsets (NOKIA are you listening? LOL). Ciao.
