we have been experimenting with different sip client on android based smart phone. while linphone works out of the box with freephoneline over both wi-fi and 3g, we can not get sipdroid working properly:
server:
- server or proxy: voip.freephoneline.ca
- 5060
- udp
audio codec:
- always try the following coec
- g722, gsm, pcma, pcmu, gsm, speex, bv16
Advanced option:
- stun server stun.ekiga.net 3478
- use mmtel flavor
- q value = 1
Pbxfeatures:
- all uncheck
sipdroid had no issue placing and receiving calls but there were just absolutely no audio on both party, is setting the voip provider on pbxes.org mandatory to tunnel the voip calls? i could not understand why would that be required?
my other guess is the codec support issue that g.711 or g.729 is not listed on sipdroid
