Missing ISDN Serial Interface and MGCP Statement

I have a 3745 ("flash:c3745-ipvoicek9-mz.124-4.T2.bin")that keeps loosing one of its serial interfaces. As a result calls cannot be sent out this gateway even though it is still registerd with the CallManager(4.1.3ES71.

The whole mgcp statement just disappears

The work around is to reload the box out of hours. How can I resolve this isssue.

Re: Missing ISDN Serial Interface and MGCP Statement

Hi, if not needing 12.4T features, you can try 12.4(3j) that is the most stable.

Else the latest in 12.4(4)T than is now T6.

Chances are the bug is fixed in both releases.

Hope this helps, please rate post if it does!

Re: Missing ISDN Serial Interface and MGCP Statement

Do you mean all the MGCP statements disappear, or is it that the D channel command 'isdn bind-l3 ccm-manager' is removed out of the configuration ?
