General

Unless otherwise is stated the information in this document is valid H.323 extensions (IP extensions using H.323 signaling). Regarding SIP extension (IP extensions using SIP signaling), see separate description SIP extension.

H.323 extension is a facility in the MiVoice MX-ONE Service Node that allows the data network to transmit voice communication. Using TCP/IP the MX-ONE converts voice into packets before transmitting them over the IP network, where they are unpacked at the other end.

Users at remote small offices can connect their terminals to the system. The MX-ONE Service Node grants access to and provide services for these terminals.
