isdn busy b-channel X <br>
as well but it didnt make any difference and I believe that was rightly so, as that one is only used in case of SIP or H323 and MGCP is back-hauling L3 to CUCM so it wont affect the channel on the gateway.<br>
<br>
Carlo, when you say disable you mean to bring back into service ??? <o:p></o:p></p>

<br>
But its not the case and eventually have to reboot the controller. <br clear="all">
Is that really how its supposed to be OR we have missed something.<br>
<br>
we are on cucm 8.5 with mgcp gateways.<br>
