The primary goal of VoIPER is to create a toolkit with all required testing functionality built in and to minimise the amount of effort an auditor has to put into testing the security of a VoIP code base. This version has been extensively tested against a variety of SIP clients but should also work versus registrars, proxies, gateways and so on.

For the moment the fuzzer incorporates tests for
 SIP INVITE (3 different test suites)
 SIP ACK
 SIP CANCEL
 SIP request structure
 SDP over SIP

This translates to well over 200,000 generated tests covering all SIP attributes specified in RFC 3261 for the given messages.

It includes other features such as
 Protocol and process based crash detection and recording
 Fuzzer pause/restart functionality (SFF)
 Supports clients that require registration prior to fuzzing
 Simple to expand to new protocols
 As far as possible, protocol compliance e.g ACKs and CANCELs responses to prevent some clients hanging
 Target process control (SFF)
