Ok, I can see,
But, in the cancel, I can't know the codec! Then, I can't select the good asterisk. I'm lost
Well, I've never seen a proxy inspecting the SDP in order to know the first codec and route based on it (of course, it's perfectly valid).
But then you ahve two options (AFAIK);
- Use proxy statefull.
- When route the initial INVITE store in a DB the "branch" parameter and the choosen destination address. You can do it with a custom SQL query using "db_query". If you receive a CANCEL it will have the same "branch" so you can query the DB and get the address.
