I noticed that my 3cx setup with the patton 4960 connected to a T1 PRI has almost a 1 second delay during conversations. We have another T1 PRI connected to our regular PBX which has almost no delay at all. What is interesting is if I call a DID on my regular PBX from 3cx there is no delay in that call (calling from one T1 to another), only when 3cx is dialing to the outside world is there a delay. I've tried swapping the T1 lines, but had the same issue. Is there anything that can be done?
