Mission Accomplished

Through continued success and expansion
Greenhous made the decision to relocate their
headquarters to accommodate their growing
team. They needed a new communications
solution installing in their new office, and across
their multiple sites.

  1. With additional users and an annual call
    volume in the region of 1 million calls per
    year, they required more reliable support for
    their telephony provision while reducing their
    annual spend.
  2. Greenhous record their calls for training and
    monitoring purposes, so with the advent of
    GDPR, it was imperative that call recording and
    storing was compliant with GDPR legislation.
  3. They needed a company with reliable SLAs
    and who were fast to deliver the solution in the
    event of a fault or issue occurring.

How we made it all come together

Pre-planning is key

Pre-planning was conducted through joined up meetings with the Greenhous team to identify, discover and plan the best solution to implement changes – confirming what would be achieved on site.

Colossal savings

Seriun installed a new enterprise grade phone system, with new IP handsets and free call packages. This meant moving Greenhous from ISDN to SIP and as a result they are now enjoying significant annual savings of £20k.
