Today, I observe this situation which prove Cisco MGCP Callmanager route list won't failover to 2nd route group when the 1st route group's T1 circuit is down.
Ie, RoutePattern 9.@ -> RouteList: RL_siteA -> Two RouteGroup: VGW1_T1 and VGW2_T2 which in turn point to the different T1 circuit in different vgw.
When VGW1_T1 circuit status get error 'TEI_Assigned' other than 'Multi_Frame_estabished', Callmanager still show this T1 circuit regsitered and never use 2nd circuit which is VGW2_T2.
So users cannot place outbound calls due to this failed vgw1-T1 circuit even though vgw2-T2 is up.
Is it callmanager limitation?
Anyone know the workaround without manual task to remove and/or re-order route group inside the route list.
My ccm is: 4.1.3
