Forced FXo Disconnect

[rchaseling]

Hi,

Is there are way to auto disconnect a call from an FXO port after a period of time using Loopstart on a 2911 using 15.1.3 IOS?

Have got a paging system on the other end of the FXO port - after dialing from an IP Phone....if the IP Phone dies not terminate the call it stays up thus preventing all further paging

Regards

Russell

There is no time based disconnect supervision. Only signal, or tone based. The paging system will probably support one.

Cheers Paolo,

The paging system send one beep about a second long to signify that the pager has been notified - would you know if there is a way I can set the port to disconnect after hearing this specific tone?

I've tried supervisorory disconnect anytone.........

Cheers

Check if the paging system can support removing battery to indicate disconnection. That would be the easist method being the default.

Failing that, one can configure the beep characteristics, as tone based method. If not documented by vendor, this can be done doign with a PCM capture on router, or a wireshark when calling, for example, from IPCP, then analyzing frequency.
