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?
