[OpenSIPS-Users] Error no audio devices available

[Khan Friend]

Hi everyone,

I have installed OpenSIPS 1.4.4 recently on a ubuntu 8.04, I have 3 UAC
configured. Two of them are SJphone which are within the same network. One
of them (Xlite) is outside the network and behind NAT. I am facing two
problems.

1. The SJphone within network works fine but user hear his own echo.
2. XLite outside network giving the error "Error no audio devices available"

The config file is as follows:
