The problem is FXO disconnect in ios 12.3 and in ios 12.4

Dear Sirs!

What is going on from relies to relies IOS?

There is a config:

voice class custom-cptone ATC

dualtone busy

frequency 425

cadence 350 350

dualtone disconnect

frequency 425

cadence 350 350

voice-port 0/0/0

supervisory disconnect dualtone mid-call

supervisory custom-cptone ATC

no battery-reversal

cptone RU

timeouts call-disconnect 3

timeouts wait-release 5

connection plar 1400

description LINE 491

station-id name line 491

As a result we get: (in one and the same router 2811 with the same FXO)

in Cisco IOS Software, 2800 Software (C2800NM-IPVOICE-M), Version 12.3(11)T, RELEASE SOFTWARE (fc2) (c2800nm-ipvoice-mz.123-11.T.bin)

#sh voice port 0/0/0

file: sh_voice_port_123.txt

in Cisco IOS Software, 2800 Software (C2800NM-IPVOICEK9-M), Version 12.4(5a), RELEASE SOFTWARE (fc3) (c2800nm-ipvoicek9-mz.124-5a.bin)

#sh voice port 0/0/0

file: sh_voice_port_124.txt

In case 12.3 we have normally working FXO-port with the concrete distinguished signals " busy disconnect", but in case 12.4 Non working FXO-port - the signal disconnect is not determine and couldn't be determine by no means.

P.S. the option timeouts call-disconnect 3 doesn't react for changes interval <0-120> - constantly 60 seconds.

Options timing sup-disconnect and timing opx-ringwait must be very good, but how they can be used in that situation ??????

Could you please help me to set up FXO!!!

Thanks in advance!
