• SIP Trunking

SIP trunking, based on Session Initiation Protocol (SIP), delivers phone and streaming media to customers equipped with SIP-based private branch exchange (IP-PBX) and Unified Communications facilities.

SIP trunking assumes an existing VoIP infrastructure is in place and customers only require transport via the internet. SIP trunks are the physical or virtual IP connections from carriers to customers; the proverbial IP version of traditional PRIs that connect to your company's call routing system.

SIP trunking environments rely on additional customer premise equipment (CPE) to register individual phone numbers and provide calling features.

SIP trunking benefits include:

• Interoperability - Customers can build systems using components such as IP phones, soft phones, and collaborative applications from multiple vendors.
• Innovation - SIP is an evolving technology that has yet to be completely defined; leaving room for innovation
• Investment protection - With many businesses having already invested in highly functional converged IP networks, SIP-enabled endpoints and proxies can be added to existing IP communications infrastructures.
