Yankee Group Study October 2007 “ One of the things we like most about TDS’ Managed IP system is that we rarely have to think about it. Basically, it’s all plug-and-play for us. We’re a very mobile office, and this system allows each or our employees to designate how they want to receive calls when they’re not in the office.” Keith Peterson Purple Door Productions

With TDS’ managed IP, we now have a reliable system that will expand as we do. We found the pricing to be in line, actually a little better, than some of the other services available. Because we didn’t incur a major capital expense, we’ve been able to invest in other areas of the agency.” Wayne Harris, President & Partner Glowac + Harris + Madison There is an increasing interest and opportunity for IP telephony managed services, as most small-to-medium-sized businesses will seek help with IP telephony management. Small-to-medium-sized businesses that outsource don’t do so purely for cost reasons, but primarily feel too deficient in the areas of IT staff and disaster recovery preparedness to take on the task themselves.
