[asterisk-dev] REGISTER uses 401 not 407?

[Ed Greenberg]

I discovered this trying to register an Audiocodes gateway onto Asterisk 
1.2.12.1.

According to the Audiocodes engineer:

So we send 401, and they do not respond, and the gateway never registers.

I'm still investigating why some of my GWs authenticate and others don't. 
If I get any packet traces that make sense, I'll feed back further.
