[App_rpt-users] No registration for peer 'ka7u' (from 96.254.195.117)

[Ron Morell]

I have a mystery connection attempt going on.  I don't know if it is
bouncing back because of a connection attempt from my node or if it is
from another device trying to call into the node.  It looks like this:

test*CLI>
[Dec 23 09:08:37] NOTICE[29328]: chan_iax2.c:6839 register_verify: No
registration for peer 'ka7u' (from 96.254.195.117)

Tried to figure out where it comes from, but end up with Verizon, which
covers a lot.  I have my cell phone turned off, just in case IaxAgent on
my phone was running in the background and was somehow trying to call
in.  So that device is out of the loop.  Just for knowing IaxAgent on
the cell phone is using this IP currently: 174.253.181.123, and calls in
just fine.

So if I have a setting somewhere that is calling out and trying to
register ka7u it should show up in my /etc/asterisk/*.conf files, I think. 
[root at test asterisk]# grep -R "ka7u" *
extensions.conf:;exten => 3001,1,Dial(IAX2/ka7u)
[root at test asterisk]#

The above is the only instance of 'ka7u' in those files and it is
commented out while I'm trouble shooting this.  I've checked through the
iax.conf files of the friend nodes I work with and commented out all the
ka7u references in the iax.conf files on those and still the connection
attempts continue.

Any ideas of what this is all about?
