With this kind of statements (and the previous ones
you made on the
subject) you only prove that you do not use mediaproxy, do not know what
it has to offer when compared to nathelper and do not care too much what
happens to it. This is why it has a README which details its capabilities
and how it compares with nathelper and what are its advantages.
nathelper has 2 more NAT tests than mediaproxy
nathelper has fix_nated_register (which is essential for some clients)
nathelper can signal flags to rtpproxy (e.g. necessary for bridging mode)
nathelper allows "SIP ping"
mediaproxy has signaling AVP
mediaproxy can deal with asymmetric clients
IMO the nathelper benefits overrule the mediaproxy benefits. IMO
asymmetric clients should be blocked (poor implementation). Of course
Cisco gateways are asymmetric, but this is no big deal, as usually there
are no NATs between gateway and proxy. And asymmetric clients do not
work behind NAT.
Conclusion: If you use mediaproxy only for natted clients then you do
not have to care about asymmetric clients in the proxy.
I'm not sure about the fix_contact() function in mediaproxy module. Does
it really change the contact for REGISTERs or does it add a received
parameter like the fix_nated_register from nathelper? If it really
changes the contact then it wont work Nokia Phones.

I don't see any real issues. It's some
work which has to be done, and
it's not really the most important thing on the todo-list, but it would
remove unneeded redundancy.
It is interesting for me to notice that all these proposals to chop down
mediaproxy come from someone who is not using it. Not from someone who is
using it and wants to improve it, but from someone who doesn't use it and
doesn't know what it has to offer, but for some strange reason feels the
need to modify it to fit his vision of things.
As a conclusion, I'm open to any suggestion that will make mediaproxy
better and easier to use. I will not agree however to any change that
will complicate my life as a mediaproxy user so that someone else who is
not using it feels better over what it provides.
Currently the fact that the contact fixing/checking is present in 2
modules doesn't bother me at all, however all the proposals I've heard
here would make a mediaproxy user's life more complicated for no good
reason and they're not worth the price IMO.
