[SIPForum-discussion] Blank call flow in SIP

[Ramachandra moorthy]

Hi All,

I am doing testing with mobile to PSTN calls via SIP.
Found all calls are mute calls.
I have tested with mobile to mobile,few calls are ok remaining all are mute.
Also compared normal call and problematic call traces,all are seems same
only.

All media IPs are re3achable from both the ends.

Kindly suggest me to analyse further to find the root cause.

Also pls clarify is  there any signaling flow in SIP for blank calls.

pls help

With Regards
