I've just tested this myself, using the command:

api originate {sip_secure_media=true}user/$ext &eavesdrop($uid)

Eavesdrop is by default in silent mode, so neither the caller or callee can hear the microphone of the person listening in.

It should actually be w0 at 500 (not @ext) which I've tested and does work but you will need to adjust your command as follows:

api originate {sip_secure_media=true}user/$ext 'queue_dtmf:w0 at 500,eavesdrop:$uid inline

Thanks for very interesting answer! 

I’m initiating the eavesdrop with a command sent via php to the control port

Where do I put the parameter you’re saying?

We use a LUA script for Eavesdrop and never had this issue.

Looking at the FS documentation, you can use w1 at ext to speak with the callee or w2 at ext to speak with the caller.

Here are the DTMF signals during eavesdrop

2 to speak with the uuid

1 to speak with the other half

3 to engage a three way

0 to restore eavesdrop.

* to next channel.

Is it possible you pressed any DTMF key during the call? If not, you could perhaps you could try w0 at ext ?

I need to enable client to eavesdrop on certain calls. The fs is in a penitentiary institute and certain types of criminals (i..e mafia related) must be listened.

I am trying to implement eavesdropping like so:

api originate {sip_secure_media=true}user/$ext &eavesdrop($uid)

(where, I hope, $ext and $uid are self-explicatory)

Is there ANY way to mute the microphone of the eavesdropper? It’s a bit of a give-away if the criminal can hear the background noise

Thanks 

Francesco
