I’m currently in the process of implementing an Asterisk IP PBX (www.asterisk.org) in my home.
At present I am using the Voipfone service (www.voipfone.co.uk) and a Yealink T28 IP Phone. See my other post if you have one of these and have had problems getting it to register properly as a SIP phone extension. I purchased the T28 specifically to try out IP telephony as i’m non too keen on IP softphones and also wanted to see if I could get a decent IP Telephone service over my non too speedy ADSL line (BT, hurry up and rollout your 21CN).
It was when trying this out, and my Nokia N95 sitting beside me on my desk that I remembered that this ubergadget has a SIP client installed on it (I understand some mobile phone providers remove this – spoilsports). Anyway, I’m with Three and after a bit of investigation I got it to work perfectly. It is just a pity that the wifi function on the N95 eats battery life, otherwise I would use this as my primary IP phone. The call quality is great, definately on a par with my Yealink IP telephone.
N95 VOIPFONE SIP CONFIGURATION
On your phone go to menu > settings > connection > SIP settings. From here edit the default profile, or create one and ensure you settings are as listed below:
Profile name: Voipfone (or whatever you want to call it)
Service Profile: IETF
Default Access point: your wifi access point (this can be defined in menu > settings > connection > access points > new access point)
Public user name: sip:voipfone account no@voipfone.co.uk
Use compression: No
Registration: When needed
Use security: No
Proxy server (submenu)
Proxy server address: sip:sip.voipfone.co.uk
Realm: asterisk
User name: your voipfone account number
Password: your voipfone password
Allow loose routing: Yes
Transport Type: UDP
Port:5060
Registrar Server (submenu)
Registrat server addr.: sip:sip.voipfone.co.uk
Realm: asterisk
User name: your voipfone account number
Password: your voipfone password
Transport Type: UDP
Port:5060
Now, go back to the connection menu and select Internet tel. (it should be just below the SIP settings options). Create a profile in here if you don’t have one and point it to the SIP profile you just created (i.e. SIP profiles should display Voipfone [or whatever you called it] ).
Now from the menu go to tools > connectivity > Internet Tel. It should display Discovering Services and show your wifi access point that you have defined. Select your access point and this should connect you to your Voipfone service via your SIP profile.
Not exactly the most intuitive process, but it should work!
If you have problems try web browsing from your N95, if this works then your wifi connection is okay. If you still cant access and you are sure you’ve entered the correct login information it is probably a router issue. I upgraded my phone to firmware V 30.0.018 recently. To check your firmware revision use *#0000# from your N95 keypad.
