Give these steps a try:

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

Incoming Calls:
-Try calling a SIPBroker number (SIPBroker - PSTN Numbers), then *010123456 , 123456 replaced with your VoXalot number. Do you receive this call, and is audio ok?

-Try entering your voxalot URI 123456@voxalot.com in the link below. Instead of you calling Echo, echo will call you so you can see how it behaves when it is an incoming call: SIPBroker - EziDial

Possible Solutions:

-If your router has UPnP I would suggest activating that rather than DMZ

-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

-Make sure there are no Internet Connection problems. Run a SpeedTest, or maybe VoIP test at TestYourVoIP.com

-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....
