We have ccm in HQ and the SRST router in the remote site. Event though Our WAN is up and our ccm is up but the remote site phones are registering with SRST router.why phones are registering with SRST rotuer? what could be the reason. how to troubel shoot. The phones will register with srts when the wan link is down or all the ccm is down but both are up? pls help me
phones will register with SRST if the keepalives the phone sends are not replied with a keepaliveACK from the primary, secondary or tertiary server. then it goes to it's last option and starts sending keepalives to the SRST router and then it will register.
