As of a few weeks ago, our phone system developed a long delay when making outbound calls- usually around 15 seconds. There is zero delay when calling internal extensions. I haven't made any system changes or modifications in that time. I've reset the system and the Patton 4114 gateway we use. I don't believe this has to do with an outgoing rule that waits a certain amount of time before dialing since I always hit either 'send' or '#'. Please help me troubleshoot this problem. I'm looking for suggestions on what settings could be responsible for this or other things to check. I'm new to 3CX (<1yr) and am still learning a lot about VoIP and this system.
