If you get your own number on SIP it is often a standard geographic
number so for people to call you it is exactly th esame as calling a
standard landline.
voip.co.uk include a geographic number in their UK package and it is
just a one off charge os £2 if I remember correctly.
If you have a SIP device you can arrange to have as many outgoing
providers as it permits (or use a service such as Voxalot). Unlike
Skype where you have to pay Skype for all your calls, there is a
choice of hundereds of SIP operators. If, for example, you make
international calls you may decide to go with a company that is not
based in the UK.

I would say that often the sound quality of Skype can be very good.
Some podcasts I listen to use Skype to link the various participants
together. However, Skype quality can be horrible too.
The quality of SIP depends, to some extent, on the choice of codec.
Some are wider bandwidth than others. All in all SIP quality is
perfectly good for purpose. I use only SIP and get no problems at all.
A problem you might get is where you are downloading a big file and
you don't have QoS on your router. I currently don't have it but I
rarely get any problems.[color=blue]

If you are going to buy an ATA then be careful to pick the right one.
Some have provision for integrating a standard landline (if oyu have
one). Some are much poorer quality than others - so you should seek
advice on this if you are not sure.
