I can’t speak to the ISP issues directly, but it is possible the iax port is blocked. You could try another like 4570 or something far off like 8103 for a test. (don’t forget to update the port in asl self service portal if you change it) But be sure the bindaddress=0.0.0.0 in iax conf first. And this could be DNS issues I guess. So, that is something to look at perhaps before anything. @ 05:46pm est 2/3/23 I do not show the node as registered. So if the user/password is correct as you say it worked at your location, something above is likely, but not limited to that. A late thought to also check on… Check if the NAT is setup for ipv4 or allows it. It could be forced or screwed-up at ipv6 or that the IP is static and the correct ip address is the address for port forwarding pointing. ---

the port only allows inbound connection to your system. if it is not Registered or showing registered then you need to check you login information in your iax.conf file and make sure it matches what is on the site. register =\> [yournodenumber:yourpassword@register.allstarlink.org](mailto:yournodenumber:yourpassword@register.allstarlink.org) ---

The more I have thought about this, I would mostly think it is not getting a network connection. Try to ping a known address, local and internet.
