[Freeswitch-users] OpenSIPS configuration for 2 or more FreeSWITCH installs

Hi , iam using this configuration http://wiki.freeswitch.org/wiki/OpenSIPS_configuration_for_2_or_more_FreeSWI... for load balancing FreeSWITCH servers, everything works fine if i use port 5060 ( user -> opensips-> freeswitch ). If i want to use other port for incoming calls from providers , let say 5080 as is in external profile in Freeswitch ( provider -> opensips:5080-> freeswitch:5080 ), how i can do that ?? maybe someone have same situation ?? or maybe i can configure gateways on internal profile on freeswitch , if that will work ?? Thanks for any info Marcin
