Re: [OSL | CCIE_Voice] TEI_ASSIGNED
If all servers are online you should be registered to you primary server, which in the IPexpert practice labs will be your sub. You show this server as down and are registered to the backup, which I would presume is your pub. Your config (from an earlier email) mgcp call-agent 177.1.10.20 service-type mgcp version 0.1you should be registered here (Primary) ccm-manager redundant-host 177.1.10.10you are registered here (first backup) -you don't have a third cucm, or second backup configured so that will always be none on sho ccm You need to troubleshoot why the gateway is not registering to the sub (your primary ccm). 1. is the ccm service activated and running on the sub? (may need to restart the service) 2. is your db replication good? (use reporting page or cli commands to check 3. to fix db you can try utils dbreplication repair all which is not the most intrusive option but often can clear up issues. beyond this lookup cisco docs on all options/methods to check/fix db replication issues 4. can you register phones to the sub? if no, you likely have db replication issues. Also, since you were able to get your gateway registered now, can you share what you did to fix it with the study group mailer so that others may benefit from what you learned? I provided a lot of recommendations and it would be helpful to understand which were helpful and applied to the error messages you were getting.

Re: [OSL | CCIE_Voice] TEI_ASSIGNED
Did you try the steps I outlined earlier? Does show ccm indicate your mgcp gw is regisyered to cucm? If not check your hostname and domain name (if set) on gw and double check the cucm config. If so it is registered you could take it a step further and remove the pri-group from the controller (and essentially all pri and mgcp config) reboot, then put it all back. Also, if this is your home lab (or if you have access) what does the pstn side of the pri config look like? Make both sides have the same isdn switch-type and the pstn side has isdn protocol-emulate network under serial interface. A reload of both routers wouldn't hurt either (before or after all the above).

Re: [OSL | CCIE_Voice] TEI_ASSIGNED
You will not be able to bring up the pri until your mgcp gw registers to cucm. In my very first reply I assumed it was already registered but I guess I should have asked. The most common reason for not registering is a mismatch on hostname. The gateway will register as either hostname (if ip domain-name not set) or hostname.domain.com (if ip domain-name domain.com). I see your hostname is CorpHQ and I didn't see the ip domain-name command in yiur posted config. In this case make sure that in cucm you list the mgcp gw as CorpHQ exactly (I always type in the correct/matching case, I'm not sure if it is actually case sensitive but why take that chance?) Use show inventory on the router and make sure cucm has the correct router model and nm/wic part numbers. If still no luck (just looking at cucm), then delete the gw in cucm and recreate it. On the gateway use ccm config server [pub ip] and ccm config to tell the gateway to download the config from cucm. After it registers you can the no ccm config and make the pri fractional. For some basics, can you ping cucm pub and sub from the gateway? Can you ping from cucm cli to the gw lo0 ip? Do you have any qos? If yes remove qos temporarily to make sure that isn't interfering. If, after all this it still doesn't work, you should take a look at router debugs and cucm traces to determine if its a config issue or a network path issue. If debugs/traces don't show any traffic you could also run a packet capture on both router and cucm to see if you are getting any traffic at all between gw and cucm.

(Note, I haven't had to use this more elaborate method in a while - if there's an error when trying to remove L3 bind from serial interface, you will need to shut the voice-port then the serial interface, run the commands above, then no shut the serial and then finally voice-port, lastly turning on mgcp). A few other notes - I typically use the ccm config method to build mgcp, then issue "no ccm config" after it is built from the CUCM download. I noticed recently in my home lab is that I was applying the command "ccm-manager switchback immediate" BEFORE letting CUCM build the full mgcp config - the issue here is that CUCM does not properly set the switchback method to immediate (even when set in the GUI, on these versions of sw/ios) and it reverts back to graceful switchback (as indicated using "show ccm"). To correct this I now apply this command (and all others extra ccm/mgcp command, such as "ccm music") AFTER config download and "no ccm config." For giggles I reapply the bind commands as well using the first set of commands at the top of this email. The last couple times I did this in practice I have not had any TEI_Assigned and now that this is my routine it takes very little extra time versus doing a minimal config and then troubleshooting mgcp later if needed. When in doubt, reset MGCP from the gui and from cli using no mgcp, mgcp. (The latter is required if you are NOT using ccm config or have removed it. Even when ccm config is left in for a full 23 channel PRI its a good idea to reset mgcp from cli.)
