Function parseSMS

Control/L3SMSControl.cpp:629–671

Parse an incoming SMS message into RPData, save everything else we need. We do this immediately upon reception of a SIP message to error check it before queueing it for delivery to an MS. Return result or NULL on failure. SIP should return error 400 "Bad Request" in this case.
