C.3.7 Configuring the SMS Channel for Two-Way SMS

For general directions on configuring the SMS channel, refer to earlier topics starting with C.3 SMS Channel Configuration. Configure the SMS channel as though it will be talking directly to the remote SMSC, with the exceptions listed in Table C–18 that follows:

Table C–18 Two-Way Configuration Exceptions



master channel keyword

Remove the master channel keyword, if present.

It is no longer needed for SMS channel configuration. 


Set to point to the host name of IP address of the SMS Gateway Server. If using the SMPP relay’s LISTEN_INTERFACE_ADDRESS option (see C.5.7 Configuration Options), then be sure to use the host name or IP address associated with the specified network interface address.


Same TCP port as used for the LISTEN_PORT setting used to instantiate the SMPP relay (see C.5.5.2 An SMPP Relay


Pick a value and then configure the remote SMSC to route this address back to the Gateway SMPP server. In the SMS channel’s option file, specify the chosen value with this option. 


Set to match the gateway profile name. See C.5.5.1 A Gateway Profile


Set to 0.

All other channel configurations should be done as described in the SMS Channel documentation.

As mentioned in C.5.1 Setting Up Bidirectional SMS Routing, the remote SMSC needs to be configured to route the SMS address, defined in the DEFAULT_SOURCE_ADDRESS channel option, to the Gateway’s SMPP server using the TCP port number specified with the LISTEN_PORT option. (For how to specify the LISTEN_PORT, see C.5.5.3 An SMPP Server.)

Note that multiple SMS channels may use the same SMPP relay. Similarly, there need be only one SMPP server or gateway profile to handle SMS replies and notifications for multiple SMS channels. The ability to configure multiple relays, servers, and gateway profiles exists to effect different usage characteristics through configuration options.
