Multipoint capable of IP-to-ISDN?

[Zachthehouseman]

In a situation where my organization would be running an HDX 8000 and utilizing Global Video Services (therefore being IP Based), would we still need a bridge such as an RMX to reach an external ISDN network for a conference? Or will integrated Multipoint actually cover IP-to-ISDN communications? I'm still rather unclear on what Multipoint actually is.

Thank you in advance.

Multipoint capability in an HDX means the video unit supports hosting multiple connections to other video endpoints in a conference call.  Those endpoints can be whatever network connections are supported/configured by the HDX and its local network.

For the HDX to connect to an ISDN site an IP/ISDN gateway is needed.  If you do a simple search of 'polycom hdx 8000 isdn' you will find numerous documents/discussions of what is available.

With optional network module (QuadBRI or PRI) HDX 8000 support calls through ISDN network (Rec. ITU-T H.320).

With optional MPPlus license HDX 8000 can host mixed IP (H.323, SIP) and ISDN (H.320) multipoint conference.
