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?
