Tested H.323 and H.323 to SIP interworking.
n
At low bandwidths this endpoint may not handle audio properly.
You can mitigate this by disabling AAC codec for this endpoint.

The endpoint does not correctly signal a deliberate
disconnection, so the MCU treats it as an unexpected
disconnection and may redial if configured to redial on
unexpected disconnections.

An H.323 call to an encryption-required conference may result
in no video or delay in starting video.

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.

Using only Siren 14 audio codec with this endpoint is not
supported. However, if the MCU does not apply this restriction,
the parties will successfully interoperate using a different audio
codec.
