My hotel in Moscow gives you a Cisco 7970 phone with your name programmed on the display. Is that cool or what.. Yeah I couldnt resist trying to hack it but they have a special firmware loaded so the usual cisco unlock sequence didnt work.
I have been using callcentric over 5 years now. very solid platform. I have only had issues with the time it takes them to release a new feature or the restrictions they have on their accounts. For regular users however it is top notch.
