The ease of use is awesome - it's like having your own personal computer! It has so many features that I can't even begin to list them all (but they are well documented).
If you want an easy-to install phone system with tons oo ffeatures for less than $5/month per user then this should be at or near top in consideration by any small businesses looking into options between SIP Trunking solutions vs traditional PBX systems such as Asterisk etc.- but don;t take my word alone when considering other providers who may say their solution does everything PasCom will do plus more!! We have been able run Voicemail via our landline phones using Google Voice which was not cost effective nor did what users wanted most -- being mobile friendly & self service without needing tech support from us 24x7.
