sbc adds port to Tel-URI causing calls to fail

 

 

Hello all!

 

Hello everybody,

We're looking at an scenario involving the SBC and apparently the built-in header manipulation ACME_NAT_TO_FROM_IP is modifying the Tel-URI (when it appears at the from/to headers) in a way that even when the port is not present there, the sbc adds it to the Tel-URI and it has been reported that calls are not being succesful.

What I would ask you guys is if the SBC is doing wrong when it adds the port to the URI even when is not present in the original message (I've searched the RFC 3966 and I've not found anything regarding ports so far), or all the URIs are meant to have a port defined and the application is failing to cope with the ports and the sbc is just working as it's supposed to.
