I have a satellite office that has reported a sporadic issue. When they receive a call it rings one time and goes to VM as they will receive the message a couple minutes later. It happens sporadically 3-4 four times a day out of 50-100 calls received.
My first thought was how many people on the phones at a time and they say it could be 1 person in the office or 5 and the issue will occur.
Has anyone ever heard of this issue.
Is it a callmanager issue or a router issue? The connection to this office is a P2P T1 and we are using a 2800 Cisco Router with a Switch Module.
