SIP Trunks

A cost effective alternative to ISDN, SIP Trunks provide flexibility and business continuity

Arrow’s SIP Trunking service through Gamma has been developed to provide businesses of any size with cost effective voice services over any dedicated internet connection without the need for large capital investment.

  • Rationalise your lines
  • Business Continuity
  • Resilience
  • Easy Implementation
  • Cheaper than ISDN

And now Gamma SIP trunks fully integrate with Microsoft Lync, allowing you to directly connect Gamma SIP trunks to the Microsoft® Lync™ platform.

This makes Gamma one just a handful of service providers in the UK that is authorised to work directly with Microsoft Lync.

Businesses need to remain conscious not only of the features that make Microsoft Lync attractive but also of the connectivity options that are essential for successful voice strategies.
