Chapter 19-Gateway Calls
Polycom, Inc.
19-9
If the endpoint is busy, the system will not try to connect the endpoint using another
protocol.
If the call is not completed after trying all possible protocols, the system displays the
number that was dialed on the calling endpoint’s screen and the reason for not completing
the call. For details, see " Connection Indications” on page 19-22 .
Dialing from ISDN/PSTN Endpoints
Figure 19-4 Dialing String and Call Flow from ISDN Endpoint to IP Endpoint
[GW Profile ISDN/PSTN number]
- the dial-in number assigned to the Gateway
Profile, including the required country and area codes.
For example, if the dial-in number assigned to the Gateway Profile is 5705555, enter this
number with the appropriate area code: 2125705555.
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. For example, enter 3456# for IP
endpoint.
To enter an IP address as the destination number, replace the periods (.) with asterisks (*) in
the format
n*n*n*n
followed by the # key. For example, if the IP address is 172.22.188.22,
enter 172*22*188*22#.
PSTN Dial-in Using GK Prefix
When connecting to an RMX that is standalone or part of a DMA solution deployment,
PSTN participants are prompted by an IVR message requesting the Destination Conference ID
followed by the # key to be entered using the DTMF input keypad.
Including the Gatekeeper Prefix in the DTMF input string enables PSTN participants to use
the input string when connecting to an RMX whether the RMX is a standalone MCU or part
of a DMA solution deployment. For a detailed description, see " PSTN Dial-in Using GK
Prefix” on page 19-9 .
Direct Dial-in to Endpoints or DMA VMR using Automatically Generated
Destination Numbers
ISDN/PSTN participants can call the destination endpoints without interaction with the
IVR of the gateway. This dialing method is enabled when the administrator configures the
Gateway Profile to automatically generate the dial string of the destination endpoint or
Meeting Room on the DMA by truncating the dial in string and replacing the truncated
digits by other digits that can be used as the destination number.
For a detailed description of the call flow when dialing the DMA using this method
, see
"Calling a DMA Direct with Automatically Generated Destination Dial Strings” on page 19-26 .
