VVX 1500 4.0.2.11307 Tested H.323 and SIP.
n Due to inaccurate timestamps sent by this endpoint, lip
synchronization cannot be guaranteed.
n When calling over SIP, this endpoint only supports the first audio
and video codecs that it advertises. If the MCU chooses a
different audio or video codec from the advertised set, the
endpoint may not be able to decode the audio or video from the
MCU.
n The endpoint does not respond properly to commands to
mute/unmute audio/video from MCU. Using this feature with this
endpoint may lead to unexpected behavior.
