  5. H.264 V20

    Is there anyway to allow H.264 video codec in V20 or any plans to bring it back? We used to have video intercoms call a ring group, and the video showed up on Fanvil X6U handsets.

    Just a general concern I want to voice - I'd be a gem to have the v18 Inbound Rule mass edit brought back in some way.
