NAME

       Net::SIP::NATHelper::Local - handle NAT/RTP forwarding in local event loop.

DESCRIPTION

       This module is a wrapper around Net::SIP::NATHelper::Base which will handle the RTP
       forwarding within the local event loop the rest of Net::SIP uses.

CONSTRUCTOR

       new ( LOOP )
           Will create the object and tell it to use LOOP as the event loop.  Will create a
           Net::SIP::NATHelper::Base object which gets used internally.

METHODS

       allocate_sockets ( ... )
           Calls allocate_sockets of the local Net::SIP::NATHelper::Base object. Takes and
           returns the same arguments.

       activate_session ( ... )
           Calls activate_session of the local Net::SIP::NATHelper::Base object. Takes the same
           arguments and returns 1 if the session was newly activated, -1 if it was activated
           before and false if activation failed.  Updates callbacks into the event loop.

       close_session ( ... )
           Calls activate_session of the local Net::SIP::NATHelper::Base object. Takes the same
           arguments and returns the number of closed sessions.  Updates callbacks into the event
           loop.

       expire ( ... )
           Calls expire of the local Net::SIP::NATHelper::Base object. Takes the same arguments
           and returns the number of expired sessions.  Updates callbacks into the event loop if
           necessary.
