IP Phone and Analog Phone FXO Disconnect Tone Issue

Hi All,

Kindly need your help. I've problem related with disconnect tone issue. Below is simple topology about the system :

Analog Phone -- Matra PABX -- Cisco Router 2821 -- Cisco Call Manager 9.0 -- IP Phone

We are using Cisco Router 2821 as Voice Gateway to connect with Matra PABX on the client. Matra PABX using FXS port to connect with FXO (VIC2-4FXO) port on Cisco Router 2821 using RJ-11 cable.

Below is spesification Cisco Router 2821 :

1. Cisco IOS Software, 2800 Software (C2800NM-ADVENTERPRISEK9-M), Version 12.4(22)T5, RELEASE SOFTWARE (fc3)

2. PVDM2-64

3. VIC2-4FXO

4. VIC2-2FXO

5. AIM-CUE

The Problem is :

When I try to call from Analog Phone to IP Phone. The call was succesfully established but after that the call will be disconnected automatically before 5 minutes and that problem appears very often.

What I've done is :

1. I've done tuning and also create custom cptone using custom frequency and cadance. I measure it using wireshark and cool edit pro to see the frequency and cadance. http://ciscoflair.blogspot.com/2009/05/cisco-fxo-disconnect-issue.html. I'm also attached Show Run and Show Voice Port on the Router 2821.

2. I've done debug voice ccapi inout and debug vpm signal after doing some tuning on frequency and cadance and below is the result :

From the debug, I found something strange on that debug

cc_api_call_disconnected Cause Value=86

I found something related with disconnect cause value 86 on this document :

Is there anyone of you have same problem related with disconnected cause value 86? Or maybe anyone have solution to fix this problem?

I really appreciated with any suggestion and help to solve this issue. I hope this discussion will be useful for everyone in the future.

Thank you very much all
