At least I believe so. First, we are saving lots of money w/ 3CX and could not be happier. The issue: We have 3 PRI's running on a Patton 4960. All inbound to DIDs are working properly to all 3 PRIs to 3CX. What is not working properly is the outbound calls. One of our PRI's is assigned a different set of number prefixes (651.925.xxxx, etc) that's outside our main prefixes of (612.673.xxxx) for the main office; we are bringing in satellite offices and keeping their prefixes local to their community..and we save the money! The issue is when I enable outbound calls for the satellite offices' PRI some of the main prefix calls try to go through the PRI for onlythe satellite offices. When this occurs, our provider sends a message that these numbers (main prefix numbers) are not allowed through this PRI. So long story short: How do I specify in 3CX for certain extensions to go through a specific PRI of a gateway device for outbound traffic? Thanks. --Rob StarTribune Network Engineer.
