What you get out of moving
A smaller bill, for a structural reason. Copper is billed per physical line, so you pay for every one whether it rings or not. Voice over IP is billed per person, and domestic calling is normally included. Most companies we migrate find lines they had forgotten they were renting.
A front door that sounds like a company. Extensions, a menu that routes to the right person, hold music, voicemail that arrives in your inbox as a file you can forward. A five person business answers like a department, which matters on the first call from someone who does not know you yet.
The phone stops being a place. The same extension rings on the desk phone, the laptop and the mobile. The office number works from home, from a client site and from an airport, and your team stops handing out personal numbers.
And the part most people forget
We inventory every analogue line you have before we touch anything, including the ones that are not phones. Alarms, elevator lines and card terminals each need their own answer, and finding that out after the copper is cut is the expensive way. We are not tied to one carrier or one platform, so what we put in front of each line is whatever fits, not whatever we resell.
