I was told about a strange issue and am not even sure where to start checking.
My experience was this…
Dial [customer number] from [cell phone] on November 16th at 10:48 AM
Wait for IVR prompt
Dial 207 to connect with extension 207
Here’s where the strange part comes in…
Instead of being connected with extension 207, I was connected with another external inbound caller who was also dialing into the system. I was not connected with any internal extension (seemingly).
Anyone encounter something like this before or know what might cause it?

For more clarification.
This customer is using Loop Start lines and is in a very small Rural town about 100 km from my office.
They are running 6.3.6.21

Has this happened before, and can you duplicate it?
The only thing I can think of is the user at 207 has DEE or is call forwarding outside the system, and when you called in it grabbed another trunk to dial out but there was a call being presented to the system, the telco just hadn't sent the ring voltage yet, and BINGO, your incoming call is connected to another incoming call. Classic loop start call collision... a rare occurrence but can definitely happen. Nothing you can really do about it, without advanced call state supervision like PRI or SIP trunks, it can happen.
If this happens a lot, then it's a sign of insufficient number of trunks for the setup, you can add more trunks or remove the users ability to use things like DEE or Call Forward off-premise.
