Severity: wishlist
At Thomson Reuters we have built a rather large Sip server in GO. And we are slowly opensourcing components. This is a sip grep package that we found very handy for monitoring sip networks with very large traffic loads 200mb+. It uses libpcap or standard pipes to read in data. It parses sip packets and allows you to filter each field in a sip message independently. It should be very useful for any voip network.
