<div>Hi,</div>

<br><br>Same telco provider. Recorded and checked the disconnect tone and both same freq and cadence. <br>Same router platform and ios version. <br>both H323 and MGCP gateways is connected on the same CCM. <br>FXO's are used for outgoing calls only.
<br><br>Setup: <br>IP phone---ccm5.0.4----3845(ios 12.4(9)T2)-----PSTN. <br><br>Configs: <br>voice class custom-cptone test <br>dualtone busy <br>frequency 480 620 <br>cadence 500 500 <br>dualtone disconnect <br>frequency 480 620
