Dialing to <strong>Polycom</strong>® DMA 7000<br />

Chapter 18-Gateway Calls<br />

Two dialing methods are available to ISDN/PSTN participants calling the DMA:<br />

• Direct with automatically generated destination dial strings from dial-in strings. This<br />

option is available only from version 7.1 and only to <strong>RMX</strong> with MPM+ and MPMx<br />

cards.<br />

• Via Gateway IVR.<br />

In addition, PSTN participants can dial the Gateway IVR and can use the MCU or DMA<br />

prefix in the gatekeeper together with the conference ID/endpoint alias as the destination<br />

string to simplify the input. This is one of the methods for PSTN participants to connect to a<br />

virtual Meeting Room on the DMA. For more details, see "PSTN Dial-in Using GK Prefix” on<br />

page 18-7.<br />

Calling a DMA Direct with Automatically Generated Destination Dial Strings<br />

In this configuration, the gateway session initiator enters one of the dial-in numbers<br />

assigned to the gateway profile. This number is truncated by the <strong>RMX</strong> gateway and the<br />

truncated digits are replaced by a prefix that corresponds either to the DMA prefix in the<br />

Gatekeeper.<br />
