Hi, I have an IP Office installed at a customer's location using a T1 with DID's and the main number is sent across the T1. the issue is, when the main number is called, there is a 30 second delay before the call hits the IP Office and when it does, the call goes to one of the DID's that is targeted to a fax extension. this is an intermittent problem. my config checks out. my incoming call route have their destinations targeted correctly. could this be the T1's programming from my provider?
