Hi everyone,

I was required to develop an interface for receiving and sending SMS messages to Dialogic's SWS server according to the [login to view URL] standard.

For this purpose I developed 2 pieces of code [login to view URL] and [login to view URL]:

receive_sms:

Receiving the XML of a segment (one of X) an SMS message decodes the message and returns the content of the message There are several examples of messages in the code

send_sms:

Receiving text of an SMS message divides it into segments and generates XML for each segment

The above processes work properly when I work with UCS2.

But in messages that are longer than 160 characters in English that should be encoded in GSM-7BIT messages of 160 characters. The messages are cut off (missing letters) or (weird characters are added) in short, the messages arrive with broken text.

The task is to fix the sending and receiving of the long messages in English.

in a normal way and without missing or adding letters (and if there are additional bugs that you did not raise in the code to fix them)

I suspect it is related to GSM 7-bit encoding with 1 bit padding but not sure

There is this article that explains quite a bit about it
