We're in the process of deploying a cloud-hosted VoIP system (Metaswitch) across our enterprise (14 locations). For it to work correctly the only change required on our part is to disable SIP ALG.
At most of our locations this has been super easy, just unchecking the box in Security->ALG and everything works. However, we have some older devices that do not have this option.
How do we disable SIP on these devices?
NetScreen 5GT (ScreenOS 5.0.0r8.1)
NetScreen-50 (ScreenOS 5.0.0r9.0)
Juniper SSG-5 (ScreenOS 5.4.0r3a.0)
ANY assistance would be most appreciated.
