In the past few months, we've started getting reports/complaints from customers about mysterious long duration calls, from 3 to 24 hours.

These show up on customer's Call History, and result in higher than actual usage... and of course, the reseller or customer has to pay for that usage.

I don't remember seeing this before a few months ago. But now we've seen it with several different customers.

It doesn't appear to be specific to a particular device... we've seen it mostly on ATA's, but also on PBX systems.

I just reported some examples to Voipo support, including some calls over 18 hours. This particular customer normally makes about 30 minutes of calls per month, but last month had several thousand minutes of these mysterious calls.

I received an unsigned reply from a Voipo agent that the calls never received a BYE, so they don't see anything wrong. So I thought I'd check with other resellers.

Anyone else experiencing this issue?
