Not able to receive 180 ringing message from the server

[arvchak]

Hi,

I tried sipdriod with asterisk it is working fine for me,even the
sound quality is good.But when i try it with a different server i am
not able to see the 180 ringing message due to which i am not
receiving SDP from the server and my client sends invite again and
again.so there is only one way audio that is from xlite to android and
not the other way.May i know what could be the reason?



Thank You
