I was recently doing a series of survival tests for one of my sites, and I noticed the following issues regarding the Cisco 7937
During Failover mode (SRST) the cisco 7937' will unregistered abnormally every 30 secs, then after few secs..it will register again, and it will continue in this cycle (if the phone was in use), we use a 7945 and we didnt have this problem, also there was another 7937 on the site, and it didnt unregistered abnormailly UNTIL you will utilize the device..also When Testing AAR the 7937 coulnt re route the calls via the PSTN, all other phones could reroute the call correctly
