Using Svmap
In this recipe, we will utilize Svmap to identify SIP and PBX devices on our target network. Svmap can also be utilized to make an inventory of all of the devices on a network. Svmap is a part of the SIPVicious suite of tools that were created in Python to audit VoIP systems and networks supporting the protocol.
Svmap has the ability to perform the following tasks:
