Our company has one Corporate and 12 branch offices. The MX250 VoIP server we purchased from Datatel360 in 2012 has proven to be an asset to our offices. We have some fairly unique needs and requirements which Michael has continued to help with being a liaison with Zultys to get us answers and support. Even though VoIP is more complex than our old PBX systems, we have had a substantial cost savings allowing us to remove 5-6 AT&T POTS lines per site.
