U should consider how many clients you will deal with per busy hour(10,20,100 you should know better ) and what is the medium time of a call (50s, 2 minutes, 5 minutes…I have no idea). After that you give me the blocking probability(2% or 1%) and with erlang B formula you will get the numbers of lines(i.e the PBX capacity)
