I am using Wireshark 1.6.3 and when I crafting a SMPP packet
according to the specification the field size of source_telematics_id 
is 1 BYTE Integer. The followings are the spec files issues.

SMPP V3.4 issue 1.2 : http://www.nowsms.com/discus/messages/1/24856.html
SMPP V5.0 : http://opensmpp.org/specs/smppv50.pdf

However, the display filter of wireshark is unsigned integer 2 BYTEs for this
field.

http://www.wireshark.org/docs/dfref/s/smpp.html

I wonder which one is correct one, but dest_telematics_id size is 2BYTES,
it is quite werid that source_telematics_id following the value of
dest_telematics_id without following its length.
