I am working with linphone call feature using Asterisk server. I have set call limit to one(1) in asterisk server for every sip users. So it will permit only 1 outgoing call and 1 incoming call at a time. Now I want to know if other user calls to user which is already busy with other call then how can I realize that, the end user is busy? Is there any way to get that using linphone lib? Or is there any way to get Asterisk HangupCauseCode using linphonelib?
I have checked with LinphoneCall.getReason() while CallEnd state but it returns null.
You should write your dialplan and save somewhere DIALSTATUS variable after dial attempt.
