I have an Inter-tel 9.115 system.

Today a caller was dropped from a hunt group on four different calls from the same number. She waited 23:35, 24:36, 26:49 and 19:20 on hold. Each time the music abruptly stops, she then hears a busy signal before the line goes dead.

I checked the diagnostics of the PRIs, but didn't see any errors at the time of the call. She was calling on a cellphone.

Not sure what else to check.

Thanks

Although you can't really do anything about it---that would be my first guess. However if many calls are doing this, from other sources and from other types of lines---then that would be another story.

I had a customer that many times he would call into his business on his cell phone and would get dropped. We tested the lines---made at least 25/30 calls from other cell phones and other places---no problem. When HE called on his cell---problems. We found out that it was a card in the cell tower of his carrier. Go figure.

Now, I'm not saying that the problem is for sure that---but cell phones are still a huge source of unreliability in phone communication. It has been tolerated so that most people think that it's "normal".

If I were you, I'd spend an hour or so testing from various sources to see if there is some sort of pattern, there. Good luck.
