VoIPtig is a great service that is simple to use, and works when you need it. The best thing about this service is I can keep in contact with my friends in the US for free as they are signed up to VoIPtig as well.
VoIPtig's technical knowledge really helped when wanting to network my companies offices together, they gave me great advice on what products to choose and explained all the functions of the IP phones.

We needed to expand our office communications and decided to switch to a VoIP service. VoIPtig networked all our phones, and not only are we saving money, but it's made internal calling, and transfering calls so much easier. Cannot recommend enough.
