The current (1.12.7) Sofia SIP has almost usable SUBSCRIBE/NOTIFY
implementation with nua_i_subscribe/nua_notify()/nua_r_notify. Instead
of using nua_notifier(), you change SUBSCRIBE to an
application-handled method with NUTAG_APPL_METHOD("SUBSCRIBE"). You
can also use NUTAG_SUBSTATE() to manage the way Subscribtion-State
header is generated.
