Hey everyone --
I have a customer with 15+ branches running in SRST mode. About half of the branches have a VPN tunnel through the internet, the other half are on directly on the MPLS (via a T1 or DSL/Net-VPN). I have a problem where each of the branches will randomly go into SRST mode, even though there is no evidence that the tunnel went down.
My keepalive on the gateway is set to 20 seconds, but the phones will take about 2 minutes to re-register with the CCM. This I can probably fix eventually, but I wanted to know if anyone else is running a gateway with SRST over a VPN to see if I need to modify my settings to prevent the site from entering SRST at all.
