P0911590 Issue 02 Enterprise Edge 2.0 IP Telephony Configuration Guide

Interoperability

Enterprise Edge IP Telephony is compatible with the ITU-T H.323v2 standards.

IP Voice supports H.323v2 Direct-routed gateway capabilities. Enterprise Edge IP

Telephony 2.0 is compatible with H.323 gatekeepers such as Radvision and the Inca

M10.

First, IP Telephony only interworks with itself and the M1-ITG. The M1-ITG is an

H.323v2 gateway. We expect future releases to support H.323 products from other

vendors.

Interoperability considerations

Enterprise Edge IP Telephony interoperates with M1-ITG and Microsoft

NetMeeting. Enterprise Edge IP Telephony interoperates with any H.323v1 or

H.323v2 compliant gateway that conforms to the specifications in the following

table.

Fax calls are only supported between Enterprise Edge Gateways.
