Hi Team,

We tested a normal message including the \n in the text

SMSC received - \n in the PDU

Now we sent a message using multi-part text >160 characters

SMSC have received \x1b (escape) character into multipart PDU before the \n. Due to this while converting request into json format it added \ begin of any special character.

Is this is an normal behaviour of adding escape sequence before the special characters in case of multi part message?

Hi,

No, that is not normal behaviour.

And in my tests, I do not see any \x1b (escape) characters.

What protocol is being used for NowSMS to communicate with the SMSC? I am assuming SMPP ... which is what I tested.

Can you provide a trace of the communication between NowSMS and this SMSC which shows this escape character being present?

Regards,
