When i want to register my 7960G or my 7912G IP Phone with callmanager, it take some minutes. I think in the first time is normal. I have two callmanger in the remote site, and a callmanger express v3.4 in the remote site ( i have configured a ccmgroup with this order : publisher, subscriber, ccmexpress). When the phone is registred with cme and connection come up, it take also some minutes to register with the publisher and vice vera. In all these case, the upgrading appear in the screen.
I have two callmanager (Pub and Sub) for redandoncy and load balancing purposes. These servers are installed in the home office and i have many sites with Voice gateway and Ip phones. i will that when there is a problem with the two ccm servers or when there i WAN otage, ip phone can register with CME, please is there any way to make this without adding CME ip address in ccm group.
Instead of configuring CME on the remote router, configure SRST (kind of slimmed down verision of CME). This way the phones will have be preserved in case WAN is down, and at the same time you wont need CME. I don't even think adding CME to CCM group is supported by Cisco.
Yes, we have used CME instead of SRST because when there is a power probelm, the config of phones will be lost in remote site when there a wan otage also in the same time. For this, we have configured the cme. But, i have two callmanager, and the third is cme ? is there any posiblity to make this config without add a ccm group ?
adding 3 ip address with option 150 can't resolve this.

the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
