Hosted PBX

Virtual PBX Service (also known as Hosted PBX Service) is designed for the small & medium business starting up and not wanting to invest in expensive phone equipment. Simply put, a hosted PBX system provides call-routing services via the internet that relieves customers from any technical complications since everything is remotely handled.

With the advent of virtual PBX, companies no longer need to invest in physical phone systems as everything is maintained remotely by a third-party communications company (TRES).

The dramatically lower cost of a virtual PBX system enables smaller businesses and “off-site” freelancers/contractors to adopt the advanced technology of bigger companies.


SIP Trunking

TRES offers SIP Trunking service for businesses where we can connect your IP-enabled PBX phone system directly to the TRES phone switch via the internet providing your company with local & international calling service at very competitive rates.

SIP Trunking allows enterprise and small businesses to eliminate a PSTN gateway at their site and outsource that function to a carrier. It is typically a lower-cost alternative to Primary Rate Interfaces (PRIs) because SIP trunks can be purchased in single-trunk increments (as compared to 30 channel increments for a PRI). Your company will reduce costs using Voice SIP Trunks versus traditional TDM lines.
