I'm using CUCM 6.1.2. Agent login Extension mobility on phone. They can press service button and enter user ID and PIN, when press submit, phone display show as login successful but phone extension not cahnge. I need to wait for a while, phone display show "registering". I have to wait for 2-3 minutes, phone can be login sucess after that.
Anyone who used to face this issue? Please advise me?
Thanks in Advance.
Either something is running slow on the system or you may have problems with replication - the login is done on your publisher, and typically your phone is serviced by a subscriber. The login from the publisher sometimes takes a little time to replicate to the other server.
An easy fix may be to just restart the servers (one at a time, leaving time for each to fully restart between them).
I'd take a look at the console logs/packet captures from the phone and see if there's something the phone is waiting for. It might be that you have an incorrect TFTP server configured or something like that.
I had a similar problem, it turned out to be differing locales. phone vs device-profile took a while for the dp or the phone to change over the locale.
Had the same problem but with CUCM 8.6 and cause was NTP servers on CUCM-P & CUCM-S were not in sync. Both servers were showing different times.
Issue resolved after we changed the NTP server IP & both servers came in sync and showing correct time.
