hi all,
i have a callmanager 4.2 and cisco 2811 as avoice gateway (MGCP)with 2 vic2-4fxo ports,
the problem appeares when some one from outside places a call into the system the line keeps ringing even when the calling party goes on hock,
although i solved this problem previously on 1760 gateway with the following commands under the voice ports;
voice-port 1/0
supervisory disconnect dualtone mid-call
cptone EG
timeouts call-disconnect 0
timeouts wait-release 1
timing hookflash-out 500
connection plar opx 0
these commands have no effect in my case
another very starnge thing happens that the command "cptone EG" disappears from the cofiguration after some time or after a reload (although i make copy run start).
so please can any one helps me to fix this issue
thanks in advance

hey,
along with your commands i also had to ask the carrier to enalbe COD on thier end. to do that, they had to put the pstn lines in a trunk and then enable COD. that worked. other than that, some say ground start works but not everytime.

Try using a custome tone to disconnect the call. This works fine for me, as i was facing the same problem as urs previously.
One thing u gotta get the frequency right according to your PBX or country dial tone frequency n cadence.
!
voice class custom-cptone test
dualtone busy
frequency 400 400
cadence 375 375
dualtone disconnect
frequency 400 400
cadence 375 375
!
voice-port 0/0/0
supervisory disconnect dualtone mid-call
supervisory custom-cptone test
!
When Ground start and battery reversal does not help in solving this issue. So we are down to using tone supervisory to disconnect the call.

i'm still didn't solve the problem.

A bug. Please upgrade IOS and if problem continues, open a case with Cisco TAC.

i think that i have the latest IOS and hereby the result of sh version command on the voice gateway
"Cisco IOS Software, 2800 Software (C2800NM-SPSERVICESK9-M), Version 12.4(3f), RE
LEASE SOFTWARE (fc3)"
so am i still need to upgrade the IOS ?

Absolutely yes. The latest IOS in 12.4 mainline is 12.4(12), in T is 12.4(11)T.
