Cisco TelePresence ISDN GW 3241¶

manawyrm bought a Cisco TelePresence ISDN GW 3241 and wanted try to offer H.320 (video telephony) -> SIP and H.323 gateway as a service.
It draws ~30W of power in idle, so 24/7 operation is probably not going to happen.

Tests with a T-View 100 showed major compatibility issues. When a call was established (which itself only worked sometimes), the resulting picture would be jittery and without any keyframes.
The reason for this is unknown and the possibility for a fix is also unknown.
