Configure Push-To-Talk capabilities in Asterisk

Hi all,

Appologies in advance if this has been posted before.

I’m trying to configure (1) push-to-talk /group talk (is this the right term used?) like features for a few extensions (i.e. 101, 102, 103) where immediately after pushing the dial button (on the soft phone), the extension will immediately log into a pre-defined conference bridge (i.e 1001). While another group of extensions (i.e 104, 105, 106) will auto login to another bridge (1002).

Later thru some API capabilities (2), modify the group to have extension (i.e 101, 104, 105) to auto login to 1001 and (102,103,104) into 1002.

Kindly advice if both (1) and (2) are feasible in Asterisk and how do i go about it. Thanks!

With regards,
