Re: SMPP Service Type --wap

There is two way to define the application type (push case)

a) the port, client port specified for push
b) X-WAP-Application-Id header, telling is the application wlm.ua or 
mms.ua

In pull, it is the phone that starts the things, so it is more like how 
server knows
that this is wap (phone knows what port it is using for the request).

Service type wap could be useful implementing wap over sms, but port UDH
tells the same thing (and is used by all protocols).
