-----------------------------------

I would be happy to do that, but is it possible for me to review my own code?

> Starting from draft 2 of RFC 5456 (October 23, 2006) plaintext auth is not supported in IAX2 protocol. Please refer to section 8.6.13 of RFC 5456.
> But plaintext auth is still supported by Asterisk implementation of IAX2. This support should be dropped.
> Attached patch, based on asterisk-dev discussion, adds deprecation warning on startup if 'auth' is set to 'plaintext', changes default values of 'auth' from 'md5, plaintext' to 'md5', and adds note to UPGRADE.txt
> Patch is safe in terms of backwards compatibility, will work even if remote peers have auth=plaintext and we have defaults.
> auth=plaintext setting will remain deprecated in Asterisk 14 and 15, and IAX2 plaintext support will be removed in Asterisk 16.
