[Freeswitch-users] Using verto between two FS boxes

[Free Switcher]

Hello,

I'm trying to route calls between two FS boxes separated by a firewall that only allows http/websocket connection.

Is it possible to use verto to connect two FreeSwitch boxes? I tried using the approaches listed on the mod_verto wiki page but the bridge application fails to originate calls tithe other box with reason "USER_NOT_REGISTETED". 

SIP over websocket would also work for me but I couldn't figure out how to configure that as an origination option in the bridge application.

Thanks,
Andy
