Video Protocol The video connection protocol, both transmission (Tx) and
reception (Rx), the device is using. Possible values include:
• H.261—H.261 is an ITU standard designed for two-way
communication over ISDN lines and supports data rates
which are multiples of 64Kbit/s. H.261 supports CIF and
QCIF resolutions.
• H.263—H.263 is based on H.261 with enhancements
that improve video quality over modems. It supports
CIF, QCIF, SQCIF, 4CIF and 16CIF resolutions.

endpoint is connected. When multiple endpoints are
connected through the device's embedded MCU, this field
displays a concatenation of each endpoint's H.323ID
separated by ' | ', for example 'ISDN-CO1-7-1 | Vsfx-9-1'.
Far Site Number The address of the far site device to which the selected
endpoint is connected. The address value for the calling
