Yes, that's how I do it. > A native Symbian IAX client for the Nokia which would use Wi-Fi (or packet > data connection!) would be the way forward. Ignore SIP entirely.

Yes, that would be better, but a SIP to IAX adapter on the phone would be less work. The SIP client just needs to register to localhost. No need to develop a user interface for a separate IAX client. Btw, there are other options such as Fring, which I believe uses a proprietary protocol from the cellphone to Fring servers, which is then converted to SIP, Skype, Yahoo etc. I live in the middle east, and the state run ISPs block SIP using deep packet inspection technology. Moreover mobile data packages are so expensive that it's cheaper to make a cellular call. > > Here's an amusing thought: My Nokia E90 has a SIP client built-in, and it > doesn't support the GSM codec - only G711 and G729!

Maybe you had a weak wifi signal and the phone ramped up its radio Tx power? _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
