[Freeswitch-users] Scale UP Freeswitch

[Saeed Ahmed]

Hi,

1. i am thinking to use kamailo in front of FS boxes, is there any
difference between kamailo and opensips?

2. if kamailo or opensips is running in front of FS, then will it send call
to FS with original customer ip? so i can do billing etc on FS box

-> actually i do IP based authentication and also ip based billing on FS
box, so in case, i recieve kamailo ip on FS box then i'll loose the original
customer overview.

thanks
