Hello, to clarify a bit more on the original question: it is indeed allowed to have a port in the To header URI, but it is not required to have a port in the To header URI.
>From that perspective, you can consider that you are "not forced" to set a port in there, the SBC has to work with a To URI without port. Usually the issue in such case is that they configured the SBC to use the To URI for routing, which is a wrong approach, they must use R-URI for routing.
