i was using iPhone and pjsip 1.5.5. i think the same would work in 1.0.3. I know i could not get it to work initially with 1.0.3 either. After i got it to work with 1.5.5 there was no reason to go back to 1.0.3. hope this helps Alex -------------- next part -------------- An HTML attachment was scrubbed...
