Incoming call on FXO disconnect issue

[ahmed-mujeeb]

Hi,

I hava a CME 7.0 setup with VIC2-4FXO card, I am using b-acd ivr for incoming calls,

First issue is whenever anyone dials in from PSTN and just disconnect after the call connected to ivr.. the call doesn't disconnected but the FXO port remains off-hook and after some time the operator phone rings that is set in the param operator.

Second issue is if the PSTN caller disconnect the call after dialing any extension after IVR the phone still rings for 5 to 6 rings and then disconnected.

Highly appreciated and thanks in advance.

Regards,

Ahmed Mujeeb

Hi Ahmed,

I see you have uploaded a pcm.dat file from that I was able to decode that you are using

CALLER-ID Time: 11/28 12:16 Phone: 213-431-1909

Countries: "US", "AU", "CA", "HK", "SG"

have you tried cptone for your specific country.

Let me know the name of service provider and I can check for cptone config.

Hi Ahmed,

Try this:

voice class custom-cptone ptcl
 dualtone disconnect
  frequency 449
  cadence 350 345

voice-port 0/1/0
 supervisory disconnect dualtone mid-call
 supervisory custom-cptone ptcl

Do a shut and no shut after this.

Let me know how it goes.
