[asterisk-users] Asterisk/GXW410x IP Analog Gateway

[Nitesh Divecha]

Hello All,

I am trying to setup a small system where Nextone Softswitch will send 
traffic to Asterisk and then terminate on Grandstream GXW410x IP Analog 
Gateway but for some odd reasons the call are flashed back from 
Grandstream to Asterisk and creating a Black loop...

I did follow the instructions provided by Grandstream support but it 
doesn't seems to be working...

OS: Ubuntu 8
Asterisk 1.4.22.1

Anyone implemented Grandstream GXW410x IP Gateway with Asterisk and can 
share config?

Cheers,
Nitesh
