What our customers say

Having to make crucial operational decisions, within hours of the latest government announcements, were trying for us all. OVERLINE were there for us. Using the latest technology to enable us to continue working remotely throughout lockdown and beyond. The charity raised £250,000 in the first 3 months of lockdown on a remote set up thanks, largely, to the functionality of our telephone system and the accompanying account management provided.”
Ryan Heal
CEO of Rockinghorse
We have used OVERLINE for our phone system for approx. 3 years now and would recommend them to anyone looking for an effective system backed up with first class account management. This is epitomised by having someone at the other end of the line when we need them, something hugely lacking elsewhere these days. However, it was really during the first phase of “lockdown” that our relationship with OVERLINE really came into its own with endless support.
