I am still waiting for my number to finish porting successfully. In the meantime, I was able to set up Anveo E911. However, as it was the first step to set up Anveo, I changed the default choice on Obitalk from SP2 to SP1. I did not realize that SP1 is the primary and SP2 was optional. I hope this is simply a trivial thing and will not impact the use of or ability to set up service. My competency in understanding VoIP extends no further than simply following directions, so I feel like any mistake should be scrutinized. Thanks for your input. Gabe.
It makes no difference they are interchangeable. In ObiTalk you can pick which one you want as primary.
