If I use a domain name as **external\_media\_address** like ```auto [test-transport] type=transport external_media_address=myexternip.com ... ``` the domain is not going to be resolved. I found it in the session part of SDP (o= …) How to resolve the issue? (Of course the domain points to my (dynamic) public ip) ---

This was fixed in the latest release. The domain name is now resolved and can be configured to re-resolve regularly[1].

Ah, you are correct. It was only fixed for the c= line. Please file an issue[1] that it should also cover the o= line. Generally though I’ve never come across anything that actually cares, but something may be out there. [1] [https://issues.asterisk.org/jira](https://issues.asterisk.org/jira) ---
