As many other happy owners of one of latest (well, it was released more than year ago, but it is still quite modern) gadget from Nokia, I could only use a fraction of its features, which it has in abundance. There are some rarely used (has anyone ever used “barcode scanner”? ), some just not frequent, but some of them are just not easy to use. And some have bugs despite it has been a long time since phone’s firmware was first released.
Device has WI-FI. And SIP VoIP client. And I was desperate to find a way to make cheap, or, better, free international calls. Finding VoIP provided isn’t hard – there are plenty of them around, and I am currently with JustVoIP (free landline calls to some countries, particularly to one I am interested in, guess which one), but getting communicator working with it was something similar to playing DOOM 2 on “Nightmare”. Yes, every time, again and again, I was getting wise error message “Unable to connect to the connection server”. No explanation why and what to do about it.
You, probably, already came across small truckload of Nokia SIP setup guide, but still could not get that working, as I did. Well, this is not because these guides suck, they just miss a point.
Before configuring SIP, make sure you switch Wireless power saving off. On my Nokia it was of by default, which, I guess leads session initiation to break when phone thinks nobody uses WiFi.
To switch power saving off, go to: Settings->Connection->Wireless Lan->Option->Advanced settings. Power saving option will be at the bottom, switch it off.
Now you can return to your provider’s connection guide and repeat attempt. A couple of other points I also noticed are:
- Always enter your public name as xxxx@myvoipprovider.com, where xxx is username or SIP number they provided to you. Don’t forget to replace myvoipprovider.com with your provider’s domain name
- It may be worthwhile using server IP address instead of domain name in proxy and registrar server options
- I could not find how “Realm” affects the connection
- User name is case sensitive!
In my case, justvoip started to work right after I switched power saving off. Voip quality rocks – people on the other side of globe think I somewhere much closer 
Dude, can you tell me what are your settings for justvoip? I’m trying to config my n95 but till now I got no success on connecting Internet Phone. Best regards
Hi mate,
I can only tell you my JustVoip settings; they should be similar to InternetCalls and many others:
In Connections->SIP settings:@justvoip.com I noticed the format of this line is important
Profile name – anything you like
Service Profile: IETF
Default access point: Your access point name, I use my home WIFI
Public user name: sip:
Use compression: no
Use security: no
Proxy server:
Proxy server address: sip:sip.justvoip.com
Realm: sip.justvoip.com
User name
Password>
The rest is unchanged
Registrar server:
Proxy server address: sip:justvoip.com
Realm: justvoip.com
User name
Password>
The rest is unchanged
That worked for me.
I noticed that sometime you may need to play around realms; in some cases I had to remove them to get SIP working.
Make sure you disable Wi-Fi power saving
Hi,
I am able to make local calls without international dialing code prefix.
however as soon as I add the dialing code prefix +358 and the number (for finland) or 00358 and the number, the call doesn’t go through.
I wanted to know, how you made international calls, i.e calls to another country…
G’day Varun,
I think this is pretty much up to your VOIP provider. As far as I am aware, +(prefix) works fine for JustVOIP and for Internetcalls too. At least +7812 (Saint-Petersburg) works fine for me from Australia.
You better check with your provider, they migh have weird dialing rules.
i am trying to configure Talkfree with the SIP service Can u plz help
why my phone put 1234567890@voipbuster.com if i need call to a normal number?
george,
Didn’t you press “Internet call” occasionly?
the problem is that i want dial to a normal number, i can’t because put after a number @sip.voipbuster.com , and said “conection error” why?
george,
Do you dial the number or pick it from contact list or history?
My Nokia adds that @bullshit to every number I called to via voIP and stores them in that way in history.
i dial the number +1603xxxxxxx and the phone dial +1603xxxxxxx@sip.voipbuster.com , and said “conection error” why?
Don’t know, really.
Did not see that, except when I chosen “Internet call”
