We run a centralized call manager environment with H.323 gateways to remote voice routers. When the WAN fails the phones go into SRST and register with the router. Rebooting the router during an SRST event seems to break SRST. After the reload the phones do not register with the router.
What are the possible causes of this? I'm not able to review a remote router while the WAN is down and haven't been able to troubleshoot the issue.
The phone DHCP server is remote, but a router reload would not cause the phones to lose their IP configurations right?
The router initially connects to call manager to get the phone configuration, are the phone configurations stored in flash? Does the router need to reconnect to call manager foloowing a reboot in order for SRST to work correctly?
Any help is appreciated,
Thanks!
