Dialing to Polycom® RealPresence DMA System
Two dialing methods are available to ISDN/PSTN participants calling the DMA:
●
Direct with automatically generated destination dial strings from dial-in strings. This option is
available only to Collaboration Servers with MPMx cards.
●
Via Gateway IVR.
In addition, PSTN participants can dial the Gateway IVR and can use the MCU or DMA prefix in the
gatekeeper together with the conference ID/endpoint alias as the destination string to simplify the input. This
is one of the methods for PSTN participants to connect to a virtual Meeting Room on the DMA. For more
details, see
PSTN Dial-in Using GK Prefix
.
Calling a RealPresence DMA Direct with Automatically Generated
Destination Dial Strings
In this configuration, the gateway session initiator enters one of the dial-in numbers assigned to the gateway
profile. This number is truncated by the Collaboration Server gateway and the truncated digits are replaced
by a prefix that corresponds either to the DMA prefix in the Gatekeeper.
