DPMA unanswered handshake

[dixoncb]

I can't get my D40 to connect to DPMA. A tcp dump on the server shows the phone repeatedly sending a handshake packet, thus:

DMPA is reporting as installed in the CLI, with a valid license. I am connecting to an Azure-based development VM from a D40 behind NAT. Everything works fine when I set the phone up from the web-based local address (192.168.1.78) - it just won't play with Asterisk/DPMA. I'm using Asterisk 13.

Howdy,

You're not by chance already working with Digium's Support department on this, are you?

Cheers

Sorry I missed this.

No, we're not working with support, but it's OK. We only have a small number of these phones and we're now configuring them using the internal webserver.

Thank you for following this up.
