Description:Using CVS checkout from 2004-01-19, trying the OReilly simple sip setup however trying to find a software linux client.
The from address is bogus however I don't think the server
should crash with it.

Asterisk doesn't support subscribe.. hrm
By: ww (ww) 2004-01-20 14:00:53.000-0600

there is logic to handle subscribe messages...

but the From header in the message send by kphone is
suspicious... will try to duplicate...
