I don't understand what's the issue here. If you send the number as 123 
it arrives on the phone as 123, if you send it as +123 it will arrive 
as +123. So is this not good enough??


in GSM transmission, a from number is the originator of the number. it 
can be of different type. In reality any phone number is specified by 3 
parameters which are:

TON: type of number
NPI: network plan indicator
Address:

A short ID is nothing else than TON = shortid while an international  
number (+...) would be TON=international.
the receiving phone would display the + if the originator has 
TON=international set but not if TON is unknown or national or shortid.

In Kannel, if your number starts with +, it will set TON=international 
automatically. At least thats the case in SMPP. In EMI it puts 00 
instead because EMI doesnt support TON field and only knows 
international numbers as numbers which start with 00... (international 
prefix in europe).

So the correct approach for CIMD would be to set TON=international only 
if the number starts with +. If this is not the case, then this is a 
bug to be fixed but forcing it to another type is for sure not the 
right approach.
