Invosys has added SIP trunking to its Number Manager product, enabling inbound service management through the customer's existing platform.
Users can order SIP trunks, manage inbound services and view traffic reports while reducing call costs.
"Our wholesale model has evolved with the industry marketplace," stated Sales Director Steve Glaister.
"Invosys SIP offers the same functionality as hosted IP telephony that a customer can use on their own kit without the need to replace their existing infrastructure.
"By adding SIP Integration we apply the features customers currently use on their inbound services to SIP numbers."
