[OpenSIPS-Users] Using Dispatcher with destination as a host name

[John Quick]

Sorry. My mistake. The dual INVITE was reported in ngrep because this server
has bonded eth ports, not because of anything in OpenSIPS.

Hello John,

So, after the  ds_select_domain("2", "0");  , when doing first relay(); ,
you see 2 INVITEs going out ? Are the 2 INVITEs the same (check the branch
param for the top most VIA).

Also, add an xlog() just before the relay() printing $ru/$du and $branch[*]
- to see all destinations.
