i did some research online and found that many ppl actually tried this method to receive and make unlimited call within US and canada... i know there is an app for google voice already(dialcentral), but my question is could we get the native SIP on n900 to work wif google voice???

this is my approach:

i created a free account from sipgate.com and forwarded all my google voice call to it. then i created a free account from sipsorcery.com and linked the sipgate account to it and from there i set up the SIP account on my n900 so now sipsorcery will do all the outgoing and incoming call. i put in the dialplan, set up everything and made sure my n900 is connected to my sipsorcery account. i then tried to call using the sip just like i used to make a normal phone call and it worked!! my other phone rang and i picked up... and here is the problem... on my n900, i couldn't hear anything but on the other phone i could hear everything... i just dun understand what i did wrong... i tried different dialplan, which i dun think it s the cause to this problem.... and i tried different settings on my n900... and by the way, i m not connecting through wifi... i m using tmobile 3g... the voice quality from the other phone which i could hear is excellent... i dun wanna give this up becos i m so close to getting it fully working on my n900... i just wish someone can give me a pointer...

edit: i went ahead and did more research on this matters... and i found that it has something to do with the STUN or NAT... but i m reli getting tired of this... can someone help me out here?? thx in advance.. and srry for my typing... i use alotta IM-words lol...

Just a small suggestion but did you try something like this?

"This VoIP engineer" got as far as you (one way audio), and gave up. I find it easier with the Skype client, and being able to use my cell phone's number as the caller ID, just make life easier. I can live with the $3/mo to get unlimited calling added to my $29/mo 500 minute plan.

I also tried getting sipgate working with some other trunk services I have, to no avail. However I haven't tried since the latest update(s). Whenever I get a free "weekend" to waste, I may revisit.

Good luck with that though.

As far as I know there is a problem with the SIP . but it was fixed (According to the bugzilla that I read a couple of weeks ago - search talk.maemo.org. The question that will still remains whether this fix will be included in the next firmware release PR 1.2 ???

I use GV + SipSorcery + Sipgate without any problems. What I suggest is setting up a softphone (Linphone) and putting in your sipsorcery credentials. Then test to see if that works properly. If it doesn't and you have the same issue, then you know the N900 is not the problem. If it does work, then you may need to look at the advanced settings on your SIP account that you should have added to the N900. You may need to look up a STUN server.

Here is all the info you should need:

good luck

Maybe I'm missing something here but what is the point of the sipsorcery step?

lol, all I had to do on the N810 was GV + Gizmo5 (which GV natively supports) + Native SIP client. I recommend looking up the old guides, it might work for N900 also.. However if you want DTMF tones the N810 SIP client could not do them very easily (but could) and the superior FRING app could not do them at all, making it impossible to receive incoming calls!

SipSorcery eliminates the need for the GV ring back. SipSorcery does it seamlessly. Without sipsorcery, you would have to dial your GV number first to make calls, or use an app that would ring you back. SipSorcery allows you to use your phone as you are used to without dialing anything special, or requiring you to receive a call in order to make a call.


Also, it allows for 7 digit dialing for local numbers.

I also have G5, but you still can't make free outgoing calls through GV without jumping through hoops. With Sipsorcery it is all free and seamless. Once you get it set up properly, you can just call like you normally would, and as long as you have an internet connection, you can place calls for free.



I set the same thing up on my N800, and although the built in softphone wasn't great, I was able to make free calls.


N900 is much better for all of this, especially if you have a data-only cell plan.

for incoming:
i forwarded google voice => gizmo5 => built in sip client

for outgoing:
i installed "the one ring" which uses google voice's callback system seamlessly with contacts and the dialpad
