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>

Carlo, when you say disable you mean to bring back into service ??? <o:p></o:p></p>

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>
