Voxalot / Vono / Ipkall / Fwd / Netelip

[andrerio]

Hello everyone... Here is my problem... or what I am trying to setup.

Services I use:
Vono: Por que falar de outro jeito? (Braziliam VSP with DID in Brazil)
http://www.netelip.com (EU VSP with DID in Spain)
FREE IP Calling with IPKall (FREE DID in Washington State been forwarded to my FWD SIP Account right now.)
FWD | Home (FWD)

HARDWARE: ZyXEL P2602HWL-61C (Conectabox 4000P)
Conectabox Zyxel P2602HWL-61C

The Current Setup:

The router above has option to setup two VSP accounts with it. So I can register with two VSPs.
SIP account 1 configured with my VONO account. Works fine! I can make and receive call on my Brazilian DID using VONO on line 1.
SIP account 2 is configured with my FWD account and also works just fine! I can make calls and even receive calls through my DID from IPKALL that is forwarded to my FWD account via SIP URI.

The Challenge:

ATA LINE 1 -> VONO Incoming (DID) /Outgoing calls
ATA LINE 2 -> Register with Voxalot to make calls through my VSP's (WORKS!) but my ATA Line 2 won't ring anymore!

I signup with a VSP called NETELIP (link above) to make and receive calls. I also got a Spain DID number from this VSP. I was assigned a SIP URI from this VSP in the following format... <netelip_userid>@sip.netelip.com
With all this in mind I thought... "Now I can just replace the FWD info from IPKALL and just enter the new SIP URI from NETELIP and I'll have IPKALL forward the calls to my NETLEIP SIP URI." WRONG!!! IT DOES NOT WORK !!!



So I went further...

With this barrier holding me back I went for help with VOXALOT!
I created a FREE Voxalot account. Added all my VSPs to it. Created all sorts of Dial Plans and changed the SIP ACCOUNT 2 (Line 2) settings on my ATA so it will register with Voxalot. Done and everything works great! Or maybe! I don't know.
I can pick up the dial tone and dial everything! Works and dial plans also works. But since I don't have neither FWD nor NETELIP been registered on my ATA my phone will NOT RING !!!

THE BIG QUESTION???

HOW CAN I HAVE THIS SETUP AND HAVE VOXALOT RING MY ATA ???
IF I CONFIGURE MY ATA LINE 2 TO REGISTER WITH NETELIP INSTEAD OF VOXALOT WOULD I STILL BE ABLE TO USE VOXALOT DIAL PLANS AND ALL VOXALOT STUFF?

THANKS EVERYONE IN ADVANCE FOR THIS HELP!
