Hello there! I'd like to remap a specific cause code 501 receives on leg B to 503 on leg A. I see some documentation with proto_specific_hangup_cause into a specific extension but it's not clear how to write this for a specific map and keep the other as passthrough. Do you have any example? Thank you! Regards, Igor. -- L'absence de virus dans ce courrier électronique a été vérifiée par le logiciel antivirus Avast. https://www.avast.com/antivirus
