The ability to have multiple options of conference call dial-in numbers available at any given time makes this service ideal for my business! I love that it's so easy (and free) as well - no need to purchase expensive equipment or pay monthly bills just because you want an extra line in your office phone system!! It allows me access from wherever is most convenient while also giving great customer support when needed too :) nothing really bad about anything with CCB but maybe if we could get more lines per account? Also would like other services such as voicemail included somehow instead having them charge us separately each month again which can be very costly depending upon how many people are using their product/service during certain times throughout our day etc..
