BRI on MGCP using ISDN

[liam_mcd78]

Hi

We're trying to configure ISDN services on BRI ports using MGCP on a cisco 2821

The ISDN services have been tested and signed off by the telco but we can't get the ports to come up on the router

The best we can get is up down but if we run "no mgcp" then "mgcp" all BRI's show as down.

The config we were using is below and below

isdn switch-type basic-net3
isdn point-to-point-setup
isdn incoming-voice voice
isdn bind-l3 ccm-manager service mgcp

We also found this document on cisco's website

http://www.cisco.com/en/US/docs/ios/12_3/vvf_c/interop/int_bri.html

And have configure it like below

Configuring the BRI Interface as an MGCP-BRI Backhaul Endpoint

SUMMARY STEPS
1. enable

2. configure terminal

3. interface bri slot/port

4. shutdown

5. isdn switch-type basic-net3

6. isdn bind-L3 ccm-manager service mgcp

7. no shutdown

8. no mgcp

9. mgcp

10. exit

This also doen't work

Your help would be greatly appreciated

For BRI, you should use H.323 or SIP.

MGCP is flacky, or non-working at all.

Try adding

'isdn static-tei 0' to the BRI interface.

and performing a no mgcp/mgcp

We have 2 remote sites with multiple BRI circuits working perfectly using MGCP to CUCM, with SRST fallback on the local 2811/1861 Router.

Cheers,
