I have inherited a program that uses asterisk 1.8 to interface between SIP and a radio. I am pretty new to Asterisk. The existing system uses a custom channel driver to communicate to the radio. This channel driver code includes a Buffer and a VOX analysis to know when the SIP user is talking, thus signaling to key up the radio when a noise is detected.
We are upgrading to V16 and the existing custom channel drivers are being removed and replaced with a commercial E&M board which has its own channel driver. The board has some VOX triggering capability, but it is not working as expected and it might just be easier at this point to put our VOX and buffer in the new channel driver. But, would it make more sense to put it in a new bridge and then use the VOX bridge and the regular bridge to link the calls? ONce again I am pretty new to this.
IS there any existing VOX and buffer implementations in Asterisk or third party?
