This is a hard one to explain. My home PSTN line is connected via an Openvox A400P card to my Asterisk 220.127.116.11 box which then routes incoming calls to my 2 SCCP extensions.
The calls are routed just fine, but when a call is answered at one of the extensions or externally (by a home telephone) the asterisk extensions continue to ring one more time. Is there a way to have Asterisk drop an incoming PSTN call as soon as it’s answered?
CLI output when receiving a PSTN call: Starting simple switch on ‘DAHDI/3-1’
