SIPp is a free Open Source test tool / traffic generator for the SIP
protocol. It includes a few basic SipStone user agent scenarios (UAC
and UAS) and establishes and releases multiple calls with the INVITE
nd BYE methods. It can also reads custom XML scenario files describing
from very simple to complex call flows. It features the dynamic display
of statistics about running tests (call rate, round trip delay, and
message statistics), periodic CSV statistics dumps, TCP and UDP over
multiple sockets or multiplexed with retransmission management and
dynamically adjustable call rates.
