Optional:
[MCU prefix in SIP Proxy][GW Profile ID]*[Destination Number, first
participant]*[Destination Number, second participant]**[destination
number]......*[Destination Number, tenth participant]@domain name
For example, if the GW Profile ID is 2000, the domain name is service.polycom.com, and the

destination number is 3456, enter: 2000*3456@service.polycom.com.
If using the IP address of the RMX signaling host (for example, 172.22.188.22) instead of the

domain name enter: 2000*3456@172.22.188.22.
To invite two participants IP: 3456 and ISDN: 9251444, enter:

2000*3456*9251444@service.polycom.com.
To invite two participants IP: 3456 and PSTN: 9251234, enter:

912000*3456**9251234@service.polycom.com.

Gateway IVR

Can be used by IP endpoints when the destination dialing string includes the address of the

MCU only. This is the same flow as the dialing method used for ISDN/PSTN calls, however

it is less recommended for IP participants. For details, see page

Dialing from H.323 Endpoints

Dialing String and Call Flow from IP Endpoint to ISDN Endpoint

[MCU prefix in GK] - the prefix with which the RMX is registered to the gatekeeper.
[GW Profile ID] - The ID of the Gateway Profile to be used for the gateway call and the

IVR message.
The dialing string format is:
[MCU prefix in GK][GW Profile ID]
For example, if the MCU Prefix in the GK is 91 and the GW Profile ID is 2000 enter: 912000.
Once the participant is connected to the Gateway Profile and hears the IVR message

requesting the destination number, using the DTMF input keypad, the participant enters the

number of the destination endpoint followed by the # key. PSTN numbers are identified by

an * before the number.
For example, enter 3456# for IP endpoint, or 9253456# for ISDN, or *9253456# for PSTN

phone.
