I've never looked into that but by default
it does not. I thought I would
need "symmtric signaling" in order to define a peer in my Asterisk sip.conf
file but that turned out not to be necessary.
i was asking because of nat detection. it turned out that nathelper
nat_uac_test("3") does not check port number whereas mediaproxy
client_nat_test("3") requires that both ip address and port in via match
source ip address and port. so if call comes from cisco gw, ...
i surfed on cisco's web pages, but could not find any command that would
make gw's signaling symmetric.
