Advice/Help needed... I'm looking to use freeswitch to sbc or possibly proxy connections to my calix ONTs. Currently the ONTs have public ips that talk to a Metaswitch. But the sip clients occassionally get a "sip" "sip" ring only message. They appear to be an exploit attempt to gain the passwords to make free calls. I want to setup the sip clients on invalid addresses and pass all the traffic thru freeswitch to avoid outside contact directly to the sip clients. Is this more sbc or proxy? Can freeswith pass the user auth from the sip clients directly to the Metaswitch or do I have to have individual accounts setup on the freeswith to do this? Details on where to set this up and how would be helpful. Thanks for the newbie help. Loren
