Why asterisk not properly working with android sip client?

14,066

Thanks for every one in this forum for anticipating...I have manged to solve the problem...The two devices "xlite/zoiper" and "android native sip" client uses different default audio codecs.

default codec for xlite is BroadVoice-32

default codec for zoiper is GSM

default codec for android is G.711 uLaw

As these devices should use same codec while communicating with each other..In my scenario these devices were using different codecs which results in one way audio (when calling from android to xlite/zoiper). While creating the SIP accounts in sip.conf while we can enforce two communicating clients to use same audio codec in following manner.

[211]
deny=0.0.0.0/0.0.0.0
secret=123456
dtmfmode=rfc2833
canreinvite=no
context=incoming-calls-wildcard
host=dynamic
nat=yes
type=friend
port=5060
qualify=yes
callgroup=
pickupgroup=
permit=0.0.0.0/0.0.0.0
callcounter=yes
faxdetect=no
disallow=all    (disable default audio codec)
allow=ulaw   (allow uLaw audio codec)



[215]
deny=0.0.0.0/0.0.0.0
secret=123456
dtmfmode=rfc2833
canreinvite=no
context=incoming-calls-wildcard
host=dynamic
nat=no
type=friend
port=5060
qualify=yes
callgroup=
pickupgroup=
permit=0.0.0.0/0.0.0.0
callcounter=yes
faxdetect=no
disallow=all    (disable default audio codec)
allow=ulaw   (allow uLaw audio codec)

We can also configure audio codec settings on client side by selecting the same audio codec on both sides..

    Asterisk= 1.8.11.0

    Android= 2.3/4.0.3

    Android Sip client=Native Android sip client/sipdemo

    When i call from my pc using zoiper/xlite to android (native android sip client) now i can hear audio from both sides but when i make call from android to pc (zoiper/xlite) i cannot hear anything on android. On the other hand i have tested this scenario on elastix (which also uses asterisk 1.8.11.0) with no problem in audio. pc(zoiper) ip 192.168.15.27 android ip 192.168.15.71 asterisk server ip 192.168.15.118

    Sip debug when calling from android to zoiper .
