[Users] Re: [Serusers] Relaying and failure route - misrouted ACK

[Klaus Darilion]

The ACK should be loose_routed. Verify which path in your config the ACK 
packet uses:

 >         if (loose_route()) {
		xlog("L_INFO","$rm will be loose_route processed");
 >                 t_relay();
 >                 exit;
 >         };
	xlog("L_INFO","no loose_route processing for request $rm");

which clients do you use?

we can help you more, if you post a comple ngrep dump
