Setting source address SMPP

Hello, 

 

I am trying to change the source address to 672 for SMPP connection to SMS,
however the message is being set with source address 1234 which I have not
configured. How would I change the address? According to documentation there
is an option for my-number but it is not being changed. This is my
configuration

 

group = smsc

smsc = smpp

smsc-id = SMSC1

host = x.x.x.x

port = 21000

smsc-username = xxxxxx

smsc-password = xxxxxx

system-type = "WAP"

address-range = ""

my-number = 672

source-addr-ton = 4

source-addr-npi = 9

source-addr-autodetect = no

 

Thanks for the reply in advance
