[cisco-voip] BRI Interfaces

[H, Tim]

I might also mention that we're using straight through cables for this as opposed to crossover cables.

Could this be the issue? It's a remote site so I can't test.

All,

Having some issues setting up my first BRI interface.  I copied some of the MGCP gateway config below.  Is anyone out there using BRIs? Maybe you could cross-reference your config with mine.

I've debugged ISDN q931 and have not been able to see anything even attempt to enter.  After doing some research on "spoofing" it looks like it's just a way for the router to show the interface as up so all of the protocols can still run even though it is not actually up.

Any ideas would be helpful.

Show Run:
interface BRI0/0/0
 no ip address
 isdn switch-type basic-net3
 isdn point-to-point-setup
 isdn incoming-voice voice
 isdn bind-l3 ccm-manager service mgcp

Show Int:
BRI0/0/0 is up, line protocol is up (spoofing)
  Hardware is Voice NT or TE BRI

  Encapsulation VOICE, loopback not set
  Keepalive set (10 sec)
  Last input 00:00:00, output never, output hang never
  Last clearing of "show interface" counters never
  Input queue: 0/75/16703/0 (size/max/drops/flushes); Total output drops: 0
