CME : fxo line disconnecting during an active call

[Marc El Achkar]

Hello , i have a CME CISCO2921/K9 ,Version 15.3(2)T

We are facing a problem with fxo lines:

while we are on a active call, the call may get dissconnected, and it is happening randolmy on few occasions.

my fxo config is as follow:

voice-port 0/1/3

trunk-group Local

supervisory disconnect dualtone mid-call

input gain -3

output attenuation -3

echo-cancel coverage 64

cptone OM

timeouts initial 5

timeouts interdigit 5

timeouts call-disconnect 3

timeouts ringing 5

timing guard-out 300

connection plar 0

description Line8

caller-id enable

anyone faced this issue , can it be a bug or missconfig of cptone?

We have other CME's in the same area and we are not facing these issues, the only difference is this router has the latest version installed.

Take "debug vpm signal" with "term mon" for a dropped call.

I do have it but its very long and can't find how can i attach it , i just post it all or is there a way to attach it?

You can to post only the portion about the call that has been dropped. Not the full log.
