Anyone have detailed instructions on how to get an Avaya J169 3PCC OpenSip working on freePBX 16

I’ve been trying to get this phone working on my PBX and it’s been stuck at acquiring service. Any helps appreciated

Provisioned via the phone keypad, via the web interface, or some other means?

Using UDP, TCP or TLS transport?

What, if anything, appears in the Asterisk log when the phone attempts to register? If nothing, run sngrep and report what, if anything appears there. If also nothing, capture traffic at the phone and report what network activity is present.

UDP and provisioned using the phone keypad. I’ll catch the lot tomorrow.
