Problem - I can´t hear and they can´t hear me

I have the following problems.
1. When I make a phone call to a PSTN line people can´t hear me and I can´t hear them.
2.If someone phones me on my voxalot number they can hear me and I can hear them.
3. I can dial a pstn line and it ring the other party, but we cannot hear each other.
4. If I dial another voxalot user nothing happens.

Does this have something to do with the NAT SUPPORT PARAMETERS?
I´ve seen on some tutorials to specify most of this setting in NO, but I realized that when doing this I could not hear nor other voxalot users could hear me.
But if I specify this parameters in YES, then I could talk to other voxalot users.

Which setting should I setup on NAT SUPPORT PARAMETERS? (I dont know what are these parameters for, but I guess that the problem is here)

Could someone help please?

Im using a sipura spa-2002 connected to a router.
My current NAT SUPPORT PARAMETERS are:
Handle VIA received YES
Insert VIA received YES
Subsitut VIA Addr YES
Stun Server: stun.xten.com
EXT RTP Port Min: blank
Handle VIA rport YES
Insert VIA rport YES
Send Resp To Src Port YES
Stun Test Enable NO
Ext IP: blank
NAT Keep alive Intvl 28
