We've upgraded from CM 4.1.3 to CUCM 7.0(2a) and all the data has been imported successfully but the problem I have is that every IP phone I try and register it just sits there 'registering'. All the data looks good, and there were no errors on import and the publisher issues a DHCP address and TFTP firmware upgrade to the phones without any issue - but they just wont register!! Ive tried 7940,12, and 70's but they all have the same problem. Ive also tried diasbling CTL etc but makes no difference. The only change I can think of between the two call manager versions are the names - ver 4 was called CCM_PUB1 whereas the version 7 is CCMPUB1 (same for the subs) - I dont know if this would make any difference?
First thing that comes to mind is that the phones get a list of servers from TFTP - this includes the names or IPs as specified under the 'System/Servers' menu in CCMAdmin.
If that menu has names (e.g. CCMPUB1) then the phones need to resolve that to IP via DNS - if this is how thing are running, it's possible the DNS entries haven't been updated since the upgrade and name change?
If that is the case (check the System/Servers menu, and if it's listed by name, then try pinging each name as it is listed), then you have two choices:
1) Update DNS (do this anyway, sooner or later)
2) Change the server names to IPs (carefully! get it wrong and you will have a fun afternoon) and then reset all the phones

Not using CTL, just tried disabling the service (read this somewhere that it could make a difference). All the phone settings are correct in terms of IP addresses, gateway, TFTP servers etc and pinging is fine. Haven't grabbed a capture yet but it's probably the sensible next step!!
Huge thanks to you guys for trying to help me out here - it's really appreciated. Well, the good news is that it's now working and the reason that things weren't working was due to the Software License Version not being completed - I'd forgot to register the product! DOH!!!!!!!
Oh well, live and learn - at least I wont forget to do that again!
The short answer is that you don't.... That isn't entirely true while at
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...
