We have several remote branches on v4 and v5 clusters. The phones at the remote branches periodically re-register due to what appears to be TCP timeouts on the KeepAlive requests.
The only devices which I have access to at these remote branches is the ISR's terminating the local PRI's, so I can't check to ensure the QoS configs. I'm wondering what the best course of action is at this point. It doesn't seem that adjusting the "Station and Backup Server KeepAlive Interval" and "Station KeepAliveInterval" service parameter settings would correct the TCP timeouts, but wanted to get some advice.
