Hangup After First Ring Using Asterisk Call Files

votes

Default Asterisk configuration (only sip.conf changes).

I use call files for calling and I need to hangup after first ring while every dial.

WaitTime: 4 seconds doesn't work sometimes, since it's counting from the beginning (connect to SIP provider etc) and the client doesn't even receive the call.

00359894000001.call

Channel: SIP/flowroute/00359894000001
Extension: 00359894000001
WaitTime: 4

There are no way predict connection time and count how much ring was at called side. Ring create by endpoing equipment, you have no control/info about it.

If the connection time for the SIP provider etc is constant you should just check what it is and add it to your 4 seconds.
