Outgoimg Calls: Can you reach *600 (Echo Test)

Yes, It works fine and I can make out going calls through ActionVOIP and Gizmo5 without any problem

I can receive the calls, but I can’t hear audio, but other end can hear me.

I do not get the call / ATA does not ring

-Preferably make sure you have STUN set up (stun.xten.com has been working for me)

-This is optional, but it may help to open these port ranges and forward them to your ATA's IP:

5050-5064
5000-5005
16300-16500 (this maybe slightly different for your ATA, there should be an RTP port range setting on your ATA, if it is different, note the range and open that range instead in your router...)
For some background on this see: http://forum.voxalot.com/12685-post20.html

- I have enabled UPnP and deactivated DMZ
- I can’t set up STUN as provision is not there in ATA
-Forwarded ports (5060 and 16384) to ATA

-If Nat Symmetric Handling is set to NO and Optimize audio to YES (these are both settings in your VoXalot account), try setting Nat Symmetric Handling to YES and Optimize audio to NO (or vice versa)

-Make sure that the codec string you have set up matches what the provider supports (personally I've had good results with this string: ulaw;alaw;g726;g729;ilbc;gsm, give it a try )

Hopefully one of those things will help things along....

- Speed tests shows rating of >4 and QoS of more than 85%

- If I toggle Nat Symmetric handling to "No", I could not check echo test. Hence changed it back to "Yes".

Thanks again for the help.
