[Freeswitch-users] Application to Record Calls - Out of Band

Hi Matt,

FreeSWITCH probably isn't what you want.  A quick Google for 'sip call
sniffer' found this: http://www.enderunix.org/voipong/ which might well
be a more appropriate starting point.

A SPAN port is just a port on a network switch which has the traffic
going to/from another port (or ports) replicated to it.

Cheers --

Dave
