Trying to make a sip call using an N80 is a confusing proposition. I've read in places that SIP is a) supported b)not fully supported c)supported but unavailable due to configuration issues on some networks. Which is it? When I try to call the registered N80 phone from a PC client I'm getting a 488 error returned from the phone. I interpret this as meaning the phone cannot handle the codecs proposed or more likely the call over WLAN itself.
suggests that I'd have to write an application to do this using the C++ API, however as they say the RTP headers and libs don't seem to be available? There doesn't seem to be an official Nokia statement on their intentions regarding SIP for the N80 which makes it risky to start development on an N80 SIP app if there's an official one in the pipeline. Can anyone shed some light on this for me ?
