Hi TJ,
Are you in the UK?
I notice you mention you are using this service for your business and was wondering:
Have they provided you with a UK STD Code (e.g. 0207)? Their site suggests only NewYork numbers are available.
Does your bill appear in dollars/cents or pounds/pence?
Also, after navigating their site for a while, I came across this link
http://www.ithqs.com/index-5.html where it provides a 'Great Britain' contact number. When calling it though a polite American lady tells me the number is 'temporarily out of service', which doesn't bode well
Also, what do you think about the comparisons between G729 codec (such as the service you're suggesting) and G711?
Any comments about the MOS scores between the above codecs and how they differ?
As I am sure you know business communication is far more 'mission critical' than residential so I wanted to gauge your input on these points which raised concerns in my mind when investigating this further.
Good luck
