Our Services

Personal training

Your managers and supervisors will receive one-to-one training on all our products.

We are only ever a telephone call away, and additional training for new staff can always be arranged on an ad hoc basis.

If you want all the benefits of advanced call centre technology but don’t want to make a major investment in hardware, systems and premises, then we have the answer.

Our mission at Sigma is to deliver cost-effective, resilient network telephony solutions – backed by unrivalled customer service.

We are totally committed to understanding your business and giving you the products and services you need to succeed.

Sigma monitors all aspects of its service delivery closely and robustly, to ensure you get the support and attention you need.

We keep in close touch with our customers’ changing requirements, maintaining regular contact, and continually reviewing their needs.

If you’re not totally happy, we’re not happy.
