NOKIA N95Here are my settings for the N95 and the VoIP BETA.
Select Menu > Tools > Settings > Connection > SIP Settings
Select Options > New SIP profile > Use Default Profile
Enter the following settings (where 1234567 is your SIP ID)...
Profile name: Broadband Phone
Service profile: IETF
Default access point: Your WLAN/GPRS/UMS connection
Public user name: sip:1234567@sip.plus.net
Use compression: No
Registration: Always on
Use security No
Next, select 'Proxy Server' and enter the following settings...
Proxy server address: sip:nat.plus.net (or
natproxy.plus.net)
Realm: [/b]sip.plus.net
User name: 1234567
Password: Your BETA trial password
Allow loose routing: Yes
Transport type: UDP
Port: 5082
Now press 'Back', select 'Registrar server' and enter the following settings...
Registrar server address: sip:sip.plus.net
Realm: sip.plus.net
User name: 1234567
Password: Your BETA trial password
Transport type: UDP
Port: 5060
Click 'Back' and after a few seconds (assuming you have WLAN connectivity) the account should show as registered. If you get a warning about WLAN availability then just accept it.
Click 'Back' and go to 'Internet tel.'
Click Options > New profile
Select the sip.plus.net SIP address
Call the profile something relevant (Like 'Gradwell' or 'Broadband Phone') and click 'Back' to save the settings.
Dial a number, click 'Options' and select 'Internet Call'
Please note that the 'Internet Call' option may not be present. If it isn't then there's a possibility that your provider has removed the VoIP functionality of your handset. If you are using GPRS/UMS then there amy also be restrictions at that layer that are preventing you from making calls or registering with the service.
You may also want to check to make sure that call barring is not switched on for SIP calls.

Edit: Updated the settings to make them consistent with changes that have occurred since this was first posted.
