We’re migrating from port 5060 to a more obscure port.
I’ve setup two transports, default-udp-transport that uses 5060 and alternate-udp-transport that uses the new port.
For testing, I’ve blocked via ipatables any udp inbound connections via 5060.
Seems to be working great, but I’m seeing something confusing I’d like to run by the community.
I have a Polycom phone to which the port is correctly set to the new port using alternate-udp-transport but the registered contact shows it’s using 5060. To reiterate, 5060 is blocked and I’ve confirmed that with a scanning tool.
Any idea why port 5060 would be shown in the contact?
Thanks for any insight!
