Esme address npi Option

By default, when binding as a receiver in response to an OUTBIND request, the SMPP server will specify an ESME Numeric Plan Indicator (NPI) value of zero indicating an unknown NPI. Values for this option may be specified in one of three ways,



 A decimal value (for example, 10). 

 A hexadecimal value prefixed by 0x (for example, 0x0a). 

 One of the case-insensitive text strings shown in Supported ESME NPI types 



This option is ignored unless the  is also specified. See the description of the various server_port options for further information.

The default value is the empty string.
