3 years ago This code was developed over 5 years ago and afaik pjsip does have nat64 support these days so I would check there first.
That said, this seems like an ipv4 sdp so there will be no rewriting frmo ipv6 to ipv4.
If you still think something is strange with the rewriting you would have to dig into the code.
We are not able to make a call to some networks on their LTE network.

This is what we are getting in logs. This happens only in some of the network providers (e.g TMobile) with rest of the network it works fine. Please help me to understand what went wrong.
