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@10.47.41.109 &bridge(sofia/internal/5901@10.47.41.109)

 

whisper/coach:

originate sofia/internal/5902@10.47.41.109 'queue_dtmf:w2@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@10.47.41.109 'queue_dtmf:w2@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@500

 

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