[Freeswitch-users] Is there a way to temporarily disable DTMF controls during an eavesdrop (or control an eavesdrop session with non-DTMF stimulus)?

[Steven Szeto]

Once an eavedrop session is established (e.g. a whisper/coach session), is there a way to change the eavesdrop mode to say barge-in conference (recall that we have disabled DTMF keystrokes)?

[master e0ef319] FS-7846: [mod_dptools] add eavesdrop_whisper_aleg=true and eavesdrop_whisper_bleg=true channel variables to allow you to start eavesdrop in whisper mode of specific call leg

Michael Jerris asks:

does it work if you do the set before the eavesdrop?  That set is not running until after the eavesdrop ends.

Answer:

Yes, set:eavesdrop_enable_dtmf=false, does work if it is invoked before the eavesdrop. However there are two issues:

•         The “queue_dtmf” command is now ignored, which means the eavesdrop session starts as silent monitor instead of a whisper/coach session
•         The attempt to set eavesdrop_enable_dtmf=true does not seem to reopen the DTMF listening capabilities of the eavesdrop session. DTMF keystrokes 0,1,2,3 have no effect.

The solution for me would be this:

•         Before the eavesdrop session is started, , set:eavesdrop_enable_dtmf=false
•         Introduce the ability to change the eavesdrop mode via the command line
o   E.g. eavesdrop_change_mode <uuid> [0,1,2,3]
o   Where [0,1,2,3] are the following eavesdrop modes respectively: silent monitor, coach the a-leg, coach the b-leg, barge-in conference

I can successfully create a whisper/coach eavesdrop session with the following commands issued from fs_cli:

originate sofia/internal/5401 at 10.47.41.109<mailto:sofia/internal/5401 at 10.47.41.109> &bridge(sofia/internal/5901 at 10.47.41.109<mailto:sofia/internal/5901 at 10.47.41.109>)

whisper/coach:
originate sofia/internal/5902 at 10.47.41.109<mailto:sofia/internal/5902 at 10.47.41.109> 'queue_dtmf:w2 at 500,eavesdrop:a28739d0-00f0-4a59-8c82-7a5a74ab6861' inline

I would like to temporarily disable DTMF so that the supervisor can not change the eavesdrop mode via DTMF, but this does not work:

originate sofia/internal/5902 at 10.47.41.109<mailto:sofia/internal/5902 at 10.47.41.109> 'queue_dtmf:w2 at 500,eavesdrop:a28739d0-00f0-4a59-8c82-7a5a74ab6861, set:eavesdrop_enable_dtmf=false' inline

Moreover, I have a GUI app that presents the supervisor with the ability to change the eavesdrop mode. When he presses the appropriate icon in the GUI, I would then like to reenable DTMF and change the eavesdrop mode on the session:

Uuid_setvar a28739d0-00f0-4a59-8c82-7a5a74ab6861 eavesdrop_enable_dtmf true;
Uuid_recv_dtmf a28739d0-00f0-4a59-8c82-7a5a74ab6861 w3 at 500

Is there another way to change the mode of an eavesdrop session?
