# test delivery of packets through stateless proxy
# works by defining domain2leg to specify leg for domain(s).
# the 'deliver' method of the legs are redefined so that no
# actual delivery gets done but that delivery only gets simulated.
# TODO:
# - check with requests which have route header
# - check with responses (routing based on via header)
# - check that route and via header gets stripped and contact
# header rewritten
# - check strict routes vs. loose routers (manipulate URI
# and route header to simulate behavior)
# - more tests for Net::SIP::Dispatcher::resolve_uri (not
# only related to stateless proxy)
