I have a site in Hong Kong with 8 analog POTS lines connected to FXO on CallManager Express. You dial a sequence and the lines forward to the telephone company voicemail boxes. However when the sequence is activated the router sometimes has to âbe rebooted'. The onsite contact hasn't clarified or provided a debug for me to troubleshoot why they are rebooting the router. They did indicate after upgrade to 12.4.15T5 the problem still exists.
In short I haven't tried to use the telco's voicemail instead of Unity Express, has anyone else deployed this scenario and have any tips?
I already suggested replacing the POTS lines for ISDN E1 and buy Unity Express module for the router.
