It doesnt look like MGCP took control of the gateway like it should have when creating the ports. You did configure them by clicking on them in the GUI I am assuming individually? In any event, add in these commands so that MGCP will control the ports accordingly.
dial-peer voice 999000 pots
service mgcpapp
port 0/0/0:23
dial-peer voice 999001 pots
service mgcpapp
port 0/0/1:23
dial-peer voice 999010 pots
service mgcpapp
port 0/1/0:23
dial-peer voice 999011 pots
service mgcpapp
port 0/1/1:23
you will notice the tag after the "999" will indicate the ports that mgcp is controlling. Try that out, you may need to do a "no mgcp" "mgcp" after adding the dial-peers in there. MGCP should have added those for you though.

If you dont want MGCP to control a port on the gateway, get into call manager, bring up that particular gateway and delete the PRI port 0/0/0 from the gateway. Then verify on the gateway that the command "service mgcpapp" is no longer there. If it is, then get into config mode and remove the command from the voice port using "no service mgcpapp". I was on vacation last week so sorry for the late response.
07-16-2010 08:15 AM
Does "show isdn status" show the PRI functional during fallback. You should see "State = MULTIPLE_FRAME_ESTABLISHED".
Brandon
07-16-2010 08:28 AM
Yes the "State = MULTIPLE_FRAME_ESTABLISHED".
07-16-2010 10:16 AM
Is the problem with inbound calls, outbound calls or both?
Brandon
07-19-2010 12:48 PM
Busy for both...
07-19-2010 01:43 PM
What digits are you dialing for the outbound call? If you enable "debug voip dialpeer", what dial peer is being matched by the outbound call?

try adding in the command "ccm-manager config"
This command enables the router to download the xml file from the publisher. This seperates out the H323 dial peers from the MGCP dial peers if any. I cant remember if that command needs to be added before the "ccm-manager config server" or not. In any event run a "term mon" and after adding in the command do a "no mgcp" then "mgcp" and you should see the xml file being loaded into the router.

We have a IOS version issue that dont work with "ccm-manager config" and create problems...

THANKS!

I am now able to do calls from the inside to the outside.
But I still received busy signal from the outside to the inside. I will do some debug...
07-27-2010 07:01 AM
Get into Call Manager the go to Device, then Gateway. Find this paritcular gateway and click on the PRI's individually. Verify your setting are correct but then check the part that is in bold "Call Routing Information - Inbound Calls". Make sure your significant digits is defined correctly, i usually use All. Then verify you have the proper CSS defined for it that will include the paritions of your phones.
Edit: Your only problem is with being in fall back right? One more thing you should setup is more dial peers for each of the PRI's. I dont know how you have them trunked for inbound but sometimes only one PRI will get specified from the telco for inbound calls. By default I think the gateways should accept incoming calls with no dial peer configured for them but its best practice to have them configured for troubleshooting. So define another set of dial peers for each of your PRI's for outbound and inbound. Then once in fallback mode run the command "show ephone" to verify the phones are registered with the gateway accordingly.

I verify again, and the problem is there even if i'm not in fallback... So something wrong. I will have to reverify the hole configuration.

telnet to your gateway and issue the following commands and post the results here.
show ccm-manager
show mgcp
