Direct IP Dial-in
Detailed Description
Direct End Point Dialing
Detailed Description - General
Direct IP MCU Dial-in modes: IP address & extension string. Enables internet IP calls to a
MCU that functions as a Firewall Gateway (MCU is inside the Firewall zone).
The MCU supports two new MCU Dial-in strings:
• Direct End Point Dialing
• IP to ISDN Gateway Call
The Direct End Point Dialing method enables undefined dial-in participants to connect to
conferences without a gatekeeper being used for address resolution. The Direct End Point
Dialing method can be implemented with or without a Gatekeeper. When a Gatekeeper is
present it should be set to a Direct Call Policy configuration.
Conference dial-in can be achieved using one of the following methods:
• FX endpoints support the delimiter "," and not "##"
• H.323 card’s IP address##conf NID (for example: 172.22.190.162##1234)
• When the endpoint has extension capabilities available, list the H.323 card’s IP
address in the destination field and conference NID in the extension field. For
example: 172.22.190.162 as the call address and 1234 (conference NID) in the
Extension field, or 172.22.190.162 as destination IPaddress and 3116##1234 (i.e. ED
NID - 3116, Conf. NID - 1234) in the endpoint’s Extension field.
• In case the endpoint has the extension capabilities use H.323 card’s IP address as the
destination address and EQ NID##conf NID in the extension field. For example:
Test result summary for Meeting Rooms and On-Going conferences:
IP + Extension is supported on VSX3000/7000/8000, V500, FX, and VS endpoints.
IP##NID is supported on VSX3000/7000/8000, V500, FX, VS, Sony, and PVX endpoints.
Test result summary for Entry Queues:
IP + Extension is supported on VSX3000/7000/8000, V500, and FX endpoints.
IP## EQNID##NID is supported on VSX3000/7000/8000, V500, FX, and PVX endpoints.
IP to ISDN Gateway Call (without Gatekeeper)
On a network without a Gatekeeper, you can use the following IP to ISDN sting to dial-in
to the MCU:
• IP address of H.323 card##gateway prefix*ISDN number of remote ISDN endpoint.
For example (172.21.11.14##63*0141321800).
