Does anyone use or have used an offshore VA (virtual assistant) for outbound calls?

Hello BP,

I am in the process of using looking for a VA to assist with my business and one of the activities I will need from them is to make outbound calls for me. For those of you who use or have used VA's for this purpose; what technologies are they using to make these outbound calls? I know that Skype is one option but are there others as well?
