Hi all, i need to do parallel forking towards 2 different systems. When one of them had picked up the call, opensips has to be able to knows that until call is terminated. What i need is, if a second call comes again, opensips has to reply to the caller the busy tone.
Is this possible?
Also if you are expecting a second call to come in and want to send a BUSY if there is already an ongoing call then you will want to look at the Dialog modules "Exported Functions" to keep up with concurrent calls. You might want to look at them and figure out which one works best for your scenario and you can do searches on them and see examples in the mailing list.
