From afcbc93daede49f5475d37355f16210120d4b1c5 Mon Sep 17 00:00:00 2001 From: Richard Mudgett Date: Wed, 2 Jun 2010 21:05:32 +0000 Subject: Add ETSI Call Waiting support. Add the ability to announce a call to an endpoint when there are no B channels available. A call waiting call is a SETUP message with no B channel selected. Relevant specification: EN 300 056, EN 300 057, EN 300 058 For DAHDI/ISDN channels, the CHANNEL() dialplan function now supports the "no_media_path" option. * Returns "0" if there is a B channel associated with the call. * Returns "1" if no B channel is associated with the call. The call is either on hold or is a call waiting call. If you are going to allow incoming call waiting calls then you need to use CHANNEL(no_media_path) do determine if you must drop a call to accept the new call.
