I have remote sites with local PRI's for dialtone connected to centralized CCM over an MPLS cloud.
On occasion, the wan will hiccup and go down for a few seconds. During this time, the PRI will fail as well. Most times, the PRI will re-register when the WAN returns to service, but some times I will have to do a manual reset to correct this.
I am running SRST at these sites, but the outage is not long enough to trigger SRST.
My question is this: Is this expected behaviour? Also, can anyone clarify how the MGCP process works with WAN failure.
Specifically bind mgcp control and media to an interface, preferably a loopback interface if possible.
I have come across problems similar to those that you mentioned, which subsequently caused MGCP to bind to a dialer interface for ISDN Backup. When routing reconverged, and the ISDN was torndown MGCP was still bound to the dialer interface which was no longer reachable, consequently packets were black-holed.
When the problem re-occurs verify what the source address is for MGCP, run 'show ip socket' and confirm that the address is reachable. Resetting the gateway will force a download of the config and will re-registered with the highest IP address.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
