FXO Disconnect on H323 and MGCP difference?

Is there a difference with regards to supervisory disconnect tone on FXO using H323 gateway and MGCP gateway?

Problem is... Have this setup were supervisory disconnect tone works on MGCP gateway while not working on h323 gateway.

Same telco provider. Recorded and checked the disconnect tone and both same freq and cadence.

Same router platform and ios version.

both H323 and MGCP gateways is connected on the same CCM.

FXO's are used for outgoing calls only.

Setup:

IP phone---ccm5.0.4----3845(ios 12.4(9)T2)-----PSTN.

Configs:

voice class custom-cptone test

dualtone busy

frequency 480 620

cadence 500 500

dualtone disconnect

frequency 480 620

cadence 250 250

:

voice-port 3/0/1

supervisory disconnect dualtone mid-call

supervisory custom-cptone test

no battery-reversal

timeouts call-disconnect 0

timeouts wait-release 1

timing hookflash-out 50

caller-id enable

Attached is the running config and the disconnect tone recorded in case my interpretation of the freq and cadence is wrong.

Appreciate any help i can get.

Thanks!
