[asterisk-users] IAX2 order

[Danny Nicholas]

Pardon my ignorance, but couldn't you set up this provider as a "Static
peer" so he would always be first in the hash?

Unfortunately the answer is no; in Asterisk 1.6.x chan_iax2 stores
users/peers in a hash table, which as you have determined means they are
not stored in any particularly obvious order... and even if you did
determine the order, it could change in the future if the hash table
definition is changed.

Your provider really needs to use a proper authentication mechanism, or
you need to restrict that peer/user entry to their IP address(es) if
possible.
