@Alex: thanks for reply In this IPv4 world, most devices are in NAT, and it only matters if they are symmetric NAT or not.
So if 1 client is behind symmetric NAT, I want to use rtpproxy, otherwise, I do not. According to what I read from kamailio cfg, Kamailio only knows if client is NATed or not, it doesnot know the NAT type On Mon, Mar 4, 2013 at 2:46 PM, Alex Balashov <abalas...@evaristesys.com>wrote: > On 03/04/2013 02:44 AM, Khoa Pham wrote: > > @Daniel, how can the SIP proxy determine whether to use rtpproxy or >> not ? >> > > You have to set your own criteria for that.
