Cameron,
Try turning *off* Sipura NAT mapping. The onsip config files assume that
clients should not do NATing. (However, if the clients do it properly, it
will work. Sipura has many various NAT options you can turn on and off)
Note that if you configure clients to use NAT mapping, STUN, etc, your
experiences with audio may be completely related to how the clients handle
NAT, not mediaproxy. If the client itself detects its own public IP (or you
configure it manually), mediaproxy will not detect NAT and will not proxy
the call. I believe xlite default is configured with STUN.
If you want Sipura to use STUN (and thus mediaproxy only handles symmetric
NATs):
Under admin - advanced - SIP in Sipura, you will find:
NAT Support Parameters
Handle VIA received: yes
Handle VIA rport: yes
Insert VIA received: yes
Insert VIA rport: yes
Substitute VIA Addr: yes
Send Resp To Src Port: no
STUN Enable: yes
STUN Test Enable: yes
STUN Server: your stun serve
EXT IP:
EXT RTP Port Min:
NAT Keep Alive Intvl: 20
These settings should work with the onsip.org config file.

Subject: [Serusers] SER & Mediaproxy: XLite - Audio OK, Sipura - No audio
I am using the onsip ser.cfg for mediaproxy. All seems
OK when I call
between two X-Lite clients. However calls between X-Lite and a Sipura 2000
have no audio in either direction. Both the X-Lite clients and the Sipura
are on the same network behind NAT and going out to the SER/Mediaproxy
server which has a public IP. SER and Mediaproxy are on the same server.
I've tested SJPhone to Sipura and there's no audio also, so it seems like
a Sipura issue.
I've set NAT mapping enable and NAT Keep Alive enable to yes on the
Sipura.
What am I missing?
Regards
Cameron
