In the IVM Manual it states that "lines can be duplicates of the same SIP number (to handle multiple calls on the same number)......SIP lines can have multiple connections at the same times."
Does this mean I can have one SIP number and have simultaneous callers all hearing seperate IVM messages? In other words, using VOIP, how do I prevent callers from getting a busy signal? Do I utilize one SIP number (if so, how many simultaneous calls can it handle, i.e. vonage) or do I get several SIP numbers and run them through IVM? I just want to make sure we can handle potential call volume.
