[VoiceOps] Recommendation for End User Billing Service

[Mary Lou Carey]

I have a client that is looking for an End User billing service. I 
figured most of you would have some thoughts on this since you all do 
end user billing. Please let me know what companies you have used and 
what you like or dislike about each one.

Thanks,
