Chapter 15-Gateway Calls

For example, enter 3456# for IP endpoint, or 9253456# for ISDN, or
*9253456# for PSTN phone.
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#.
Dialing from SIP Endpoints
Optional. [MCU prefix in SIP Proxy] - 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.
[@domain name] - the RMX domain name as registered to the SIP
Proxy.
The dialing string:
[GW Profile ID]@domain name
Optional:
[GW Profile ID]@IP address of the RMX signaling host
Optional:
[MCU prefix in SIP proxy][GW Profile ID]@domain name
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.
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#.
Interoperability with CMA
The RMX does not register to the gatekeeper as a Gateway, therefore it is
recommended to create and use the CMA Dialing Rules to enable the CMA
Dial One Method.
