Sending Message like Text on receiver MISDN not like phone Number

[Dastgsm]

Hello,
In our country at Madagascar , operator could send message on phone with MISDN like a string not like a number. I would like to ask if it's possible to do the same thing with osmo-bts !!!

For example : They could send message with the phone and the identity on the phone is like : "Telma", "Mvola", "orangeinfo" ...with a samsung phone I could not call this identity and with tecno phone, it shows that the number is for the MISDN "telma" is 83562 and for the MISDN "Mvola" is 68652 .... The logic of this number on tecno is that , it the number on the touchscreen of the old phone without the repetition of the tape of the touch. in this, 2=abc and 3=def and 4=ghi and 5=jkl and 6=mno and 7=pqrs and 8=tuv and 9=wxyz.I send this discussion last months,> Hello,

AND someone replies me that :
Well, osmo-bts is not really the component of the network that is
handling this, but yes, the answer to your question it is possible.

What you are looking for is to set the TON (type of number) in the Short
Message that you submit via SMPP to the osmo-msc (or osmo-nitb)!!!

How to do this with your script python sms_smpp.py ?

Chears,
