#!/usr/bin/python """A stub sipserver for testing lmwsip This is a stub sipserver that implements a small subset of the sip protocol to perform unit tests. Implements the following commands: CMD> LI USER,PASS ANS< ! CMD> TI LMW ANS< ! 20-JAN-01 00:00:00 CMD> WN LMW,DUMMY,D10,+HH:MM,yyyy-mm-dd,HH:MM,DATA ANS< ! 1/10,;2/10;.... CMD> WN LMW,DUMMY,D10,+HH:MM,yyyy-mm-dd,HH:MM,DATB ANS< ! 1/10/0;2/10/0;.... CMD> LO ANS< ! All other commands result in a "?" CMD> * ANS< ? ERROR Note: for a WN command the time and date are ignored. The duration is used to calculare the number of results to send. The sip syntax for time is much flexibler. The stub only support this format!
