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.
