We have installed Cisco CUCM 9.1. We are experiencing a strange behavior with IP phones 3905 which are randomly Registered/Unregistered with the first and the second CUCM Subscriber (sometimes with the third CUCM Subscriber). The problem is that we are encoutering this issue with phones of the remote site (there is no problems with the HQ phones).
I don't think that the problem is related to the network (LAN/WAN) because we tested a 7911 phone (using SIP firmware too) which is functionning perfectly.
Have you any idea about this ?
I joined a trace collected from a 3905 phone's console :
- version 18.104.22.16800-5
- CUCM Group : SUB1 (192.168.150.2), SUB3 (192.168.150.4), SUB4 (192.168.150.5)
