I guess the difference is that the mobile operator uses a different IP
network setup, e.g. different firewall/NAT. For example, if the NAT has
an ALG (application layer gateway) and rewrites SIP messages it often
causes problems.
Some workarounds you can try:
- disable all nat_detect features and always force NAT traversal
- use a different port, not port 5060
- use SIP over TLS

Thanks for your reply.
The server is running with public IP address. But we are facing these
problem.
1. Audio can connect but can't hear audio in both sides.
2. Video connection never happens. It was processing for very long.
There is no problem when we test in home wireless network. The audio
and video connects w/o any problem. The SIP server is still the same
server which is located at data centre.
Not able to connect in 3G/4G.
Thanks for your help.

If you are using default kamailio.cfg then it should work out of the
box, you only need to ensure that your server is running on machine
with public IP address, so, it would be reachable over 3G / 4G
networks etc.
Thank you.

Dear Sir/Madam,
I need some assistance.We are developing a mobile Apps. The apps
has module for chat which consists of audio and video.
I am using Linphone for client and Kamailio for SIP Server.
When we tested it works in the same wifi only. Does not work in
3g/4G or different wifi networks. Text is ok.
Audio call is connected but can't hear audio in both sides. Same
for video. It is processing for very long. Please assist on this.
Thanks
