[OpenSIPS-Users] ACK looping back within the opensips server

[Vlad Paiu]

Hello,

The loop happens because the caller sends a bogus ACK. The R-URI 
contains your server's IP address, instead of the Contact URI from the 
200 Ok.
Either fix the caller's phone, or take a look at  the validate_dialog() 
and fix_route_dialog() function from the dialog module.
