Been working on what could be described as a "Read only softswitch" for SIP. In a nutshell I take a metric assload of SIP signaling rebuild the calls and generate a bunch of call statistics on them. System runs independent of whatever switch you are using to route traffic and as long as you're vaguely RFC compliant should work on any network. Stats are exported as SNMP OIDs and graphed in our corporate monitoring system. Stats are a little more jumpy then usual in the shots due to it being a weekend and call volume being low.

Here are the stats for our major termination carriers.


Average Call Duration - Average length of calls connected.

Answer Seizure Rate - % of calls that were connected.

Call Attempts - Count of connection attempts.
