      From what I have been told, Asterisk can handle 300 simultaneous

                        I will say "The drawback to Asterisk is you have

                        IAX and all other VoIP protocol you do not need,
                        you may disable all applications you don't use
                        and reduce asterisk to the bare minimum, but are
                        they really hurting you? I cannot compare
                        asterisk to other VoIP software because I just
                        know asterisk, but having something "more" was
                        never been a problem. Problems can arise when
                        you need a feature and you do not have it. We
                        are working in a highly competitive market where
                        we fight to the death for every single customer,
