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.

    Could definitely be upstream. We had a problem today where calls wouldn’t go through. Searching with our provider the failed calls were all going through a route to Talkie (a sip provider) Took Talkie out of our LCR table and fixed the issue.

    Had this problem with Verizon, after MONTHS of inconsistent calling we were able to pin it down to their phased implementation of STIR/SHAKEN and how our calls were presented to them. We had to make some tweaks, and everything went back to normal. Make sure either the FROM, PAID, or CONTACT headers have the IP address of your billed trunkgroup IP address, or add a diverted header to the call from the SBC. Good luck!!

    Hey everyone. The ISP (Cincinnati Bell Altafiber) said they “can’'t” make their modem a “bridge” That we have to use their modem as our router? I’m so lost. But with this, if their equipment is routing and has a firewall I have no control over what the hell am I to do?
