Asterisk dongle sms split random size

ttmuskie

When i got a long sms (checking phone usage from PCCW), the message was split in random length.  And, the order of it also random.


I,e.
it should be like this:
1111111111222222222233333333334444444444

But i got this:
111111
2222233333
3333344444444
111122222
444

Any idea?
