1. I have a Problem in ring back tone when our customers make a call to my extensions.
2. I have a problem with some customers not all, that they cannot hear each other.
3. I have a problem that some IP phones (Linksys SPA921) can receive any call and originate calls between PBXs but cannot originate calls for mobile phones or international although at the same LAN network there is soft phone (X-lite) can originate and receive all type of calls.
I attached my ASA5510 configuration for more assistance.
thank for any helping.
