I have a new configuration for SRX1400 in Head Office and there is VPN connections with three Branches (A, B and C) witch have Cisco IP Teleohony
Head Office: Cucm 4.1
Branch A: CUCM 10
Branch B: Call Manager Express
Branch C: Call Manager Express
when i connected SRX1400, everything working fine, except Branch C, all IP Phones restarting randomly
You can try running a consistant ping from branch C to the CUCM in HQ. If this helps, you have a tunnel timeout issue. Please post HQ and branch C config files for review
SInce IP phones connect over the network for its availability.
The cause for restart is related session on the FW getting cleared.
One cause of the restart could be VPn tunnel flapping to the Branch C.
Do we se any tunnel flaps ??
