[Kamailio-Users] Kamailio Newb questions

[carl Lougher]

Howdy,
I'm trying to remove the media/rtp streams from an asterisk server for natted users so would like to know if this is possible with kamailio.

Qu's:
What is the best option?
rtpproxy/mediaproxy?
nathelper?

If i use kamailio to achieve this does it mean that i still have to carry the rtp streams through the kamailio server instead?

Also will i need to change the logon info for the clients so they now logon to kamailio then i just point registrar to asterisk?

Can i use kamailio for sip trunks to asterisk and carry rtp and natted clients media streams rather than register to asterisk?

Many thanks,
Taff..
