VOIP: Ethernet interfaces on the TMG800/TMP800
From TBwiki
The 2 Gigabit Ethernet interfaces on the rear panel of both TMG800 & TMP800 are used for VoIP interfaces. They work in the same way as the dual VoIP interface in existing TMedia (TMP6400 and TMG3200). Is that correct?
Yes, that is correct in the case of the TMG800.
