[cisco-voip] T1 PRI configuration on 2921 not matching startup config

[Lelio Fulgenzi]

OK - Having a weird issue. I was pretty sure that the router config took precedence over CUCM (with respect to enabling ports).

I've got four of  the four ports configured on CUCM. So not sure why three are being configured on the router.

Very strange!

My startup looks something like this:

controller T1 0/0/0
cablelength long 0db
pri-group timeslots 1-24 service mgcp
!
controller T1 0/0/1
cablelength long 0db
pri-group timeslots 1-24 service mgcp
!
controller T1 0/0/2
shutdown
cablelength long 0db
!
controller T1 0/0/3
shutdown
cablelength long 0db
!
<snip>
!
interface Serial0/0/0:23
no ip address
encapsulation hdlc
isdn switch-type primary-dms100
isdn incoming-voice voice
isdn bind-l3 ccm-manager
no cdp enable
!
interface Serial0/0/1:23
no ip address
encapsulation hdlc
isdn switch-type primary-dms100
isdn incoming-voice voice
isdn bind-l3 ccm-manager
isdn bchan-number-order ascending
no cdp enable
<snip>
voice-port 0/0/0:23
echo-cancel coverage 64
!
voice-port 0/0/1:23
!



But after a reload, my running config looks something like this:

controller T1 0/0/0
cablelength long 0db
pri-group timeslots 1-24 service mgcp
!
controller T1 0/0/1
cablelength long 0db
pri-group timeslots 1-24 service mgcp
!
controller T1 0/0/2
cablelength long 0db
pri-group timeslots 1-8,24 service mgcp
!
controller T1 0/0/3
cablelength long 0db
!
<snip>
