I've built a FreePBX server for our small business. The system appears to be working well but before I port the numbers across I want to ensure everything is working as it should. 

We have 3 analog lines arranged with a Pilot and 2 stepping lines. We have two numbers which I plan to port (one advertised and one legacy). 

I plan to forward the Pilot number to 2Talk for a period to ensure all is well. 

My question is if I divert the Pilot number to 2Talk can I have concurrent calls? I.e. First caller dials Pilot and diverts to FreePBX, will the second caller be diverted as well while the first call is in progress?
