Had a power failure, the FreePBX computer rebooted. Now, we are having a lot of “hang up” calls on ONE line. These are where the phone rings, you answer it, and hear either a dial tone, a quick hang up or dead silence that lasts a long time. Finally somebody told us that they got a “busy signal” when I answered the line. I heard the long silence. I looked at the call logs and saw something slightly different. On the other lines, I see chan start, from analog, DAHDI, and then answer, from trunk, DAHDI, within one second, before it starts the ring group ringing the phones. On the problem line, I see chan start, from analog, DAHDI, and then chan starts from internal, where it starts ringing all the lines, and then the answer, macro-dial, DAHDI happens six seconds later.
Looking through the setup, the ONLY difference I could find was inbound routes/advanced, signal ringing was set to yes. I set it to NO, and will have to wait a bit to see if that fixes the problem. The pop-up help on this didn’t help this newbie tell what this option actually did.
Can anybody shed some light on what might cause this trouble?
