[OpenSIPS-Users] [OpenSIPS-Devel] Need Help for Opensips configuration on AMAZON EC2

[Muhammad Shahzad]

Three tips for you.

1. don't touch record_route. Let opensips decide how this should be done.
2. use nat_uac_test(19), not nat_uac_test(23), it takes care of sdp.
3. fix nat contact on reply route same as way, i.e. use 19, instead of 1. A
better approach may to define bflag in nathelper, set it in INVITE and then
check it in reply route and do fix nat contact.

Let me know if problem persists.

Thank you.
