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? On Wed, Nov 12, 2014 at 8:35 AM, Bill Ross <rossbcan@gmail.com> wrote:
Folks;
FS: 1.4.13 / OpenWrt
disable-rtp-auto-adjust (default: false) is at default.
FS is re-writing RTP to client port. Client requires same RX port as it is sending on.
Can FS “somehow” be configured to use same port as incoming RTP?
It is my understanding that rtp-auto-adjust only adjusts IP’s if foreign and, ports if outside of rtp-start-port / rtp-end-port range
Is this correct?
Should I report a bug?
