Dynamic parameters in SMTP messages

Ozeki NG SMS Gateway can operate with SMTP messages containing dynamically set SMPP parameters in the SMTP messages' header. This guide explains how you can use dynamically set SMPP parameters by sending SMTP messages - note that this feature is only available in Ozeki NG SMS Gateway 4.2.5 or above.

How to send an SMTP message containing SMPP parameters

SMTP messages' header fields (field-value pairs) carry information about the SMTP message. By adding source_addr_ton, dest_addr_ton, source_addr_npi, dest_addr_npi, esm_class and data_coding fields to SMTP messages, you can dynamically set SMPP parameter values. Have a look at Figure 1 below.

After logging in Ozeki NG SMS Gateway's SMTP server via telnet, I sent a message to +36206543212. I added source_addr_ton, source_addr_npi, dest_addr_ton, dest_addr_npi, esm_class and data_coding fields with various values.

By sending the message, these dynamic parameters will be passed to Ozeki NG SMS Gateway, and it will use them for the SMPP message's appropriate parameters. Note that you have to use decimal values.

If you do not set a parameter dynamically Ozeki NG SMS Gateway will use the appropriate SMPP service connection's configured parameters (Figure 2).

If you have left these fields blank, default values will be used.
