Carriers benefit from SIP trunking in several ways. First, there is the revenue perspective. By offering SIP trunking services, carriers can provide improved quality of service (both voice quality and service robustness) to their carrier partners and their end users/business customers. SIP trunking enables carriers to offer a VoIP service that has availability characteristics of 99.995 and mean opinion score equal to toll service 4.4 out of 5.0. This is compared to wireless services rated at 3.8.
The carrier call also generates new revenues by offering IP-based services such as hosted communications and unified messaging to businesses. In addition, SIP trunking allows carriers to develop and expand peering arrangements with other carriers that can be both a source of new traffic (additional revenue) or a cheaper way to terminate than using TDM (reducing costs).
Finally, by transitioning to SIP trunking/IP communications a carrier becomes “greener" by dramatically reducing its carbon footprint. IP communications equipment is far more efficient that TDM switches. The amount of space, heating, ventilation and air conditioning needed is less than half that required for TDM-based switching. Considering the reduced cost of the equipment and the cost of operations and maintenance, transitioning to an IP-based network can be justified on financial terms alone.
SIP trunking is not just for businesses. It serves carriers as well.
