The H.323/SIP Room Connector add-on allows you to dial out to an H.323 or SIP room system from the Zoom Client using the public IP address or SIP URI assigned to the device.
Requirements for inviting a SIP/H.323 room system to a meeting
Host account is Pro or above
At least one Room Connector port subscription (a device connected via call-out will count as one port)
Device must have an external, public IP address or SIP URI
External calls to the device must be allowed on your network firewall
Zoom version 3.5 or higher is required to use the call-out feature.
How to invite an H.323/SIP room system to a meeting
How to specify the regional data center to call out from
By default when calling out to a SIP/H.323 room system, the US data center will be utilized. To specify the regional data center, and ensure the best call quality, the IP address or SIP domain for the desired regional data center can be appended to the dial string as seen in the below examples.
[Target device IP address];rc=x.x.x.x
[Target device IP address];rc=[SIP domain]
For example:
Device IP address: 144.195.19.161
SIP Domain: zmau.us
The dialing string would be 144.195.19.161;rc=zmau.us
How to set the call speed for call-out to H.323 devices
The default call-out speed is 1920kbps (maximum). To set the call speed when using the Zoom call-out feature, you can enter the speed into the dial string as seen in the below examples.
[Target device IP address];speed=768k
[Target device IP address];speed=768000
[Target device IP address]##[E.164 address];speed=1472k
How to send DTMF tones in a call-out to H.323 devices
To send DTMF tones when connecting to a Gatekeeper, MCU, or other H.323/SIP hardware that requires a party number, conference number, or e.164 address, you can enter these in the Call-out dial string.
[Target device IP address];dtmf=[DTMF tones]
DTMF tones have a 1 second interval
Entering a "," will pause 1 second in between DTMF tones
For example:
Device IP address: 144.195.19.161 Conference Number: 15562 Password: 622
