This is a hard one to explain. My home PSTN line is connected via an Openvox A400P card to my Asterisk 1.6.2.23 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’

  • I have the same problem, and earlier discussion here suggests it’s
    insoluble.

  • Nonsense
    It is easily solved. Simply answer through a supervised extension ( asterisk ) Don’t expect analog lines to work properly with Asterisk and a POTS
    phone bridged, with the call answered on a POTS phone Technically that is a poor method of connection.
    Simply have the PSTN line go into Asterisk, and ALL analog phones in the home or business become extensions off of Asterisk

    There ARE other ways, but it requires some coding and testing to get things to work, with no real gain I am doing this to capture and screen caller ID numbers, but it is not the best solution.
