Analyzing SIP traffic

Although all production IvozProvider installations maintained by Irontec include a Homer SIP Capture Server, it is not installed in the standalone version of IvozProvider. The reason behind this is that we prefer awesome SIPCAPTURE stack running on an additional machine.

sngrep Ncurses SIP Messages flow viewer developed by Irontec is currently the preferred tool to inspect SIP traffic included in IvozProvider.

Other capturing tools

Although sngrep is our preferred capturing tool, IvozProvider ships other tools to capture SIP/RTP traffic, such as tcpdump and ngrep.
