I have a two box Partner system that suffered a power outage (local utility). After the power recovered, I had lost Voicemail, and many other system settings/processes were wacked out. I reset the ports on the Hunt Group 7, and got the voicemail back up and running. The only "critical" issue remaining is that incoming calls are dropped after the first ring or two, if not answered quickly enough. If someone picks up the line immediately, the call can be handled normally (transferred, placed in voicemail etc). But if not, the caller will hear a buzzing (rotary type tone) and then the call is dropped. Any suggestions? Thank you!
