[OpenSIPS-Users] ACK looping issue with end-point co-located with OpenSIPS

[Daniel Eiland]

Hey folks,

Just wanted to say thanks and provide an update in case others have this
issue.

The problem was essentially that the ip address was in the domain table.  I
removed it from the domain table, adding it as an alias in the cfg and
added an additional uri==myself when determining if an incoming call was
local for a local host.

Thanks again,
-Daniel
