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

[Evgeny Izetov]

I wonder if you only had enough DSPs for those 2 and 1/3 PRIs.

Well, apparently, CUCM enabling of ports overrides the router
configuration.



I did have all four ports configured. After deleting those two ports, the
running now matches the startup.



This is very weird. Is there a configuration command that says only
download configuration for the ports I’ve enabled?

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

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
