We are new to Cisco and recently inherited a Cisco Call Manager running Version 6.12 software through an acquisition. Two days ago, the Extension Mobility feature at one of the branch offices stopped working. We contacted our support vendor and were told that we needed to reboot both Call Manager servers to correct the problem. During our conversation with the support vendor, the technician stated that the Call Manager servers should be rebooted periodically but offered no guidelines as to how often. We’re interested in knowing if anyone else has run into this and if someone has any suggestions as to how often the Call Managers should be rebooted.
