2 mynetfone accounts

[mhkb]

I have 2 MyNetFone accounts for different members of my household and wanted to set them up using Voxalot on different dial plans (eg. prefix determines MyNetFone account). Both accounts have their own DID's, but since I only wanted to use 1 of the DID's, I registered for a VoxLite account. I've setup the accounts and I can dial out using the account with the registered DID, but using the other account returns a call hang-up signal. If I switch the accounts (ie. which has 'SIP Register' ticked) the other account then works, so I know both accounts work. I also have a WorldDialPoint account without DID and that works fine. Does anyone know if I need to upgrade to a VoxPro account to use 2 MyNetFone accounts for outgoing calls? I've noticed VoxPro allows me to upgrade, but will charge me $15 USD, where the original price difference was only $10 USD.
