I want to build a PTT service for our PoC Walkie-Talkie. Any suggestion for PTT server and infrastructure design?

Hello,

2 options here:

  1. Build a parallel ptt server which manages all the nuances of the radio network and accept incoming ptt requests from clients/asterisk

  2. You can use AGI scripts started from dialplan to be triggered by DTMF key pressure (eventually interfacing external server)
