Yes, from what I understand. I didn't actually do any of the
configuration, just passed on the message to someone else, who said it

Did you follow the link that said it had more information about the
change? As I understood it, this level of breakage is expected. The
IAX2 protocol had a security feature implemented which is meant to
prevent DOS attacks.
The security measure seems to require the client and server to exchange
tokens of some sort. This means that existing clients will stop working
unless they are either configured to use this new security feature, or
the server is configured to allow connections without the security tokens.

Fortunately in our case we've only had the Asterisk box up for a day or
two, and didn't have a proper phone system before that. We're still at
the "working out the bugs" stage.
