We have to replace a CUCM Publisher for one of our customers we had some issues with replications when we introduced the new server we fixed it all looks good now but we have a strange problem in some phones , phones are showing up as registered but when we call that extension internally or externally call routes to based on settings in " Forward unregistered internal or external" for that line, it appears like CM is not looking phone as registered even though phone is registered. I do have a work around if I make a small change like CSS for that line or change the Display name then it works fine. I tried bulk reset, upgrade to latest firmware, bulk change on these phones nothing works unless I go in to each phone and make a change I wonder what triggers this to CM. Hope fully it is not a bug .
Does any body had weird issue like this?
To be specific CM version is 6.1.3 2000-1.
Thanks for your help in advance.
