You want auto adjust, but what it sounds like is your don't have static
port mappings for RTP ports on your nat, This means that the SDP may say
port 12345 ip 5.6.7.8, but the NAT randomizes the port to something else
say port 44567 ip 5.6.7.8, In which case during the small window we'll see
HEY, looks like this client doesn't know how to traverse nat all the way,
we'll switch to that port making it work.  If you're unable to get NAT
working then you have to wonder if you have an ALG also, Happen to have a
SIP trace of this?
