The problem I do have however is with "call volume'. This could be masking some audio QoS issues.

You may want to check the WiFi "power setting" on your 900 and see if you're using "100mW" vs "10mW"
Sorry for the dumb question but where do you check the wifi power setting? im a very basic user

I have made Skype and SIP calls over 3G on my N900 and calls are FANTASTIC. Same call quality as regular GSM mobile.

I am super impressed. My N95 couldn't handle SIP.

im guessing 100 is the better option?

That depends...if you want a better connection, yes.

If you want to save battery, because you're very close to the router, 10mW is better.

In that settings area mentioned previosly, there is an option to change power saving, do you know exactly what that does, and how much difference it makes to performance v battery life?

Are there multiple choices in protocols that N900 can use to stream the audio with SIP calls? Don't know much about those, but I do know that SIP as a protocol has nothing to do with this.

If you want to run your SIP service through a PBX trunk, it may add some extra functionality to your SIP service, that the 900's SIP client can not provide.

Check out the instructions here for setting up a trunk on pbxes.org:

http://seethisnowreadthis.com/2009/0...android-phone/

...just ignore the "Android" part. The instructions are mainly for setting up the trunk on pbxes. Then log in to the pbxes account on the 900 with pbxes credentials, after creating an account with them.

thanks for the answer. i'll give pbx a try .... but what i need it something that should be easy. the sip application should send a caller id .... that goes through the sip server to the receiver f the call.

on my n82 and on other nokia phones (n95 for eg) ... in sip settings there is a field "public user name" .... here if i add "sip:+mymobile_no@nonoh.net" (i use nonoh) , when i make a sip call, the receiver of my call sees my mobile phone # .... not some strange no .... or private call ....

Hmmmm I login to my account on my SIP providers web site and config that there, not on my N900.

what sip provider are you using?
i use nonoh.net

there are some general account settings ... i register my mobile phone # ... but it won't forward the caller id # by default ... it needs to be sent by the sip application

with this "public user name" filled ... there id # is sent
otherwise ... the recever sees "private call" or same strange # or a call center #
