Starting out in voxalot

[nobre84]

Hi guys.. I speak from Brazil and have been using Voipdiscount service with my Addpac ap190 voip gateway for outbound calls to PSTN lines...
Recently I installed the same setup I use on both my uncle's and my sister's house, so I was trying to figure out a way to talk for free between these 3 locations...
My gateway apparently doesn't support many stuff as fancy dial-plans or different servers (to use sipbroker) so I'm giving a shot with Voxalot, it looks very promising!
My problems:
I set up my voipdiscount account in the member panel, it says registered.
I can dial 600 from my phone, but can't dial any outbound pstn, neither sipbroker (its already configured by default after dialing * I presume ? )
Sipbroker would be directly available just like the 600 and 500 numbers? Or any setup needed?

I am also not getting inbound rings after dialing my sip-logged user in voipdiscount software. BUT if I login in a softphone with my voxalot account, then try dialing from voipdiscount software, it goes through ok! So inbound does seem like a problem in my ATA config

Thanks in advance, any help appreciated!
