[OpenSIPS-Users] WARNING:rr:after_loose: no socket found to match 2nd RR

[Richard Robson]

Hi Walter.

you wll probably need to add the  alias to make the warning dissapear. 
it souns like you don't have the alias company1.sbc.mycompany.com 
<http://company1.sbc.mycompany.com:5061> for the socket, so its 
complaining, but the message is using the correct socket for egress from 
the sound of it. This is what the new 3.6 feature addresses.

Regards.

Richard
