Is it possible to connect to a SIP server via packet data and not just WLAN.
I have a N95 V20.0.015
and set up a SIP server running 3CX v5, I can connect to the server via WLAN with no problems and make calls out, this is a good start. but when i want to connect via packet data (i'm on a data only plan so no calling option) i cannot initiate the SIP registration.
the settings in phone as as following:
Profile name: 3cx
Service profile: IETF
Default access point: VF NZ Internet (packet data) (when selected to WLAN option it works fine)
Public user name: sip:firstname.lastname@example.org (my static IP)
Use compression: No
Registration: When needed
Use security: No
Proxy server address: sip:125.xxx.xxx.xxx
User name: 10
Allow loose routing: Yes
Transport type: UDP
Registrar serv. addr. : sip:125.xxx.xxx.xxx
User name: 100
Transport type: UDP
Now, as i said before this works fine when i'm in WLAN reception. But i want to use this over my packet data ie, when i'm not at home or near WLAN. But when i want to connect:
a) if i dial the number and make an "Internet call" it will ask if i want to register with my Internet telephone service (SIP) i say yes, but it will give me an error that it cannot connect because of no WLAN.
b) If i try to connect to the SIP server before making a call via "Internet tel." in the connectivity folder, it only gives me WLAN options and no packet data options, regardless of "Default access point: VF NZ Internet" option selected in the SIP configuration.
I really hope you can understand what i'm trying to say, basiclly i can use WLAN but not Packet Data.
I used Gizmo for a wile, and using this same method but including the gizmo client (but not using the client directly to make a call) it can connect via packet data, so i'm really not sure whats going on.
Can someone please enlighten me? do i have to use a SIP client to enable SIP calls via Packet data?
PS: i forgot to mention, when i do try to register to the SIP server via Packet data, the packet data icon on the phone doesn't even appear as if its not even crating a connection, but if WLAN, the WLAN icon will appear.
