Query about Voxalot Premium

[BlueDream]

Hi, with the changes coming for vox premium I'm still unsure if I need to upgrade.

This is what I'm currently doing......

I have 2 voxalot accounts each registered on the different phone ports in my router..

1st Voxalot account:

I have 1 VSP which is registered to Les.net, which has the sip register set to NO. I'm planning on adding another VSP very shortly such as PennyTel to this voxalot account, of which I think the sip register will be set to YES.
I will want to receive calls from both of these VSP's.

2nd Voxalot account:

I have 2 VSP's which are Oztell & PennyTel. They both have the sip register set to YES. I'm also planning on changing the Oztell account to another PennyTel account.
I will want to receive calls from both of these VSP's.

So for that setup will I need to upgrade any of the accounts to a premium voxalot service?

If I do need to upgrade them then which service should I use for them.

On a side note, do all the voxalot premium accounts support call forwarding??
