Remote IP Phone 3911 problem with registration on CME.

Unanswered Question
Jul 27th, 2009

Colleagues! Can you help me to solve the problem with IP phone 3911?

We are installing Cisco 2821 CCME in central office for registration SCCP and SIP phones, which placed in branch offices. Central Office and Branch Offices communicated over IP-Sec tunnels. After tunnel down and again change state to up (or after reload Cisco CME) some 3911 can't obtain registration, at the same time other 3911 work normally. Router work with high cpu and memory loading.

System image file is "flash:c2800nm-advipservicesk9-mz.124-24.T1.bin"
