Multiple GV accounts with dual line Obi302 hardware

[ScottE]

I used GV to automatically provision the Obi302 for use with the single line in my GV Workspace account.  I now need another line.

Before I add an additional line to my GV account, I want to know if GV will auto-provision 2 lines or will the provisioning of the second line merely overwrite Line No.  In the alternative can I manually setup Line No. 2.  I'm leery of it working due to authentication issues. 

If setting up Line 2 overwrites Line 1 settings, my alternative is to get an additional Obi301, which seems like it defeats the purpose of the Obi302.

TIA
