Using Voipfone.co.uk on Nokia E65

I recently bought a Nokia E65, a very classy, handy, and feature-packed phone. One of the reasons I went with this one is because it has WiFi, which I want to use for making internet-calls. The SIP client is a bit of pita though to configure, but I finally managed to get it working.

How to configure the voipfone.co.uk voip service:

General info:
Profile Name: Voipfone
Public Username: [email protected] (xxxxxxxx = your 8 digit voipfone number beginning with 3)

Proxy Server:
Proxy server address: 195.189.173.10
Realm: asterisk
Username: XXXXXXXX (your 8 digit voipfone number beginning with 3)
Password: XXXXXX (your 6 digit password)
Allow loose routing: Yes
Transport Type: UDP
Port: 5060

Register Server:
Proxy server address: 195.189.173.10
Realm: asterisk
Username: XXXXXXXX (your 8 digit voipfone number beginning with 3)
Password: XXXXXX (your 6 digit password)
Allow loose routing: Yes
Transport Type: UDP
Port: 5060

These settings allowed me to connect over WiFi to the Voipfone.co.uk service.
