Hi,

I'm trying to build an application that provides statistics of calls and call recording. Someone told me this could be done out of band with a SPAN (?) port that would replicate SIP and media packets to a separate NIC without having to actually pass the real-calls thru FreeSWITCH. It was explained that this SPAN port would in the SBC would replicate data received.


If this is done, is there a way I can utilize FreeSWITCH to interpret these packets without actually having any control of the calls? If so how? Sorry, I'm new to telco, so hopefully this post makes sense to someone.

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 --
