No. There are no limitations to the volume of call traffic you can receive in a given time period. Our network is designed to handle volume and can be scaled up if there is the need to accomodate a larger number of calls. If you think your number will receive more than 10 simultaneous calls at any given time (10 conversations going on at the same time), then please contact our technical team and they will make sure your account is set up to handle high call volume. Note that in some instances local numbers can be unable to support more than two calls at a time.
