VS-GW1600-4G doesn't route calls to Asterisk

Hi everybody!

Really need help with VS-GW1600-4G.
We have Asterisk server and I've made configuration strictly by using this manual openvox.qiniudn.com/pub/manuals/Release/..._Asterisk_Server.pdf

But still I can't get any incoming calls in my Asterisk server. What I got:
1) Gateway are registering on Asterisk Server (see the first picture)
2) When I call to sim card GSM module got it, what we can see on the second picture.
3) But at the same time at Asterisk command line we can not see anything.

Also I tryed to check it out with Wireshark utility, but still nothing happens when I calling to sim card (No packet coming from GSM).

So I'm asking you for help! Thank you!

Hi, please add me to your skype contact list, I will help you to figure it out.

I want to thank OpenVox employee Linda Li - she helped to solve this problem.

Solving is very easy - gateway didn't route calls to Asterisk because Cluster setting (System->Cluster) was installed incorrectly: Slave mode instead Stand-Alone.
So, if you have similar situation you have to do:
1) just go to System->Cluster,
2) Click on the button near "Detail" option (turn it on)
3) Choose mode Stand-Alone.
That's it. After that everything should be fine.

Thank you OpenVox! You're the best.
