SIP call re-invite messages
SIP Re-INVITE messages can dynamically add and remove media sessions during a call. When new media sessions are added to a call the SIP ALG opens new pinholes and update SIP dialog data. When media sessions are ended, the SIP ALG closes pinholes that are no longer needed and removes SIP dialog data.

About Mike
Michael Pruett, CISSP has a wide range of cyber-security and network engineering expertise. The plethora of vendors that resell hardware but have zero engineering knowledge resulting in the wrong hardware or configuration being deployed is a major pet peeve of Michael's. This site was started in an effort to spread information while providing the option of quality consulting services at a much lower price than Fortinet Professional Services.
