Chapter 19-Gateway Calls

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 19-4Dialing 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.
