Anyone ever had some outbound calls work and others don’t? It’s consistent to certain numbers like calling my cell, nope. Calling a supplier, works.
It’s odd and I don’t see any threads out there for this issue. Of course they’re likely buried under an ocean of “no outbound calls” threads.
We have two locations with the same devices and routers. The location that has issues, the location the freepbx server is at, btw. The only thing different is that the server plugs into the same ISP modem the router for that network does. As far as I understand it, the network behind the router doesn’t see the server any differently than if it was somewhere else. The ISP modem isn’t set up as a router, right?
Try to narrow it down to the carrier that is failing if you can. Helps when you have a big team using diverse carriers. Like all calls to T mobile or Sprint fail but Verizon is ok. We’ve had this before and had to spoonfeed the problem to the carrier. Eventually, your carrier will work with the upstream or end carrier and get it resolved.
