Partner with Verizon Business for a Powerful Combination
Verizon’s Carrier IP Termination is an essential element of a successful Voice over Internet Protocol (VoIP) service that transports VoIP media between IP networks and the Public Switched Telephone Network (PSTN). This allows Verizon Wholesale Services customers to quickly and easily offer packet-based telephony products and services to their subscribers. Carrier IP Termination accepts Media traffic from retail VoIP telephony providers by way of native Session Initiation Protocol (SIP) over Verizon Dedicated Internet Access products or the Public Internet. Verizon’s Carrier IP Termination enables IP transfer via a SIP interface for termination over the Verizon Business long distance network.
Carrier IP Termination Transport provides customers the opportunity to hand off long distance calls originating as non-IP, but converted to IP, or long distance calls not meeting the definition of IP originated to Verizon’s IP network for termination on the Verizon network (PSTN).
The use of the Verizon Business Global network with IP functionality and the competitive cost structure creates a powerful combination to serve the VoIP market.
How It Works
Customers can choose to interface with the Verizon IP Network via the Public Internet, Dedicated Internet Access (DIA), or SIP Internet Access (SIA). An IP SEC Tunnel and the ability to support a P-Asserted ID is required for this application regardless of the interface type chosen. Verizon manages the billing of this traffic by building internal customer specific trunks between the Verizon IP Network (CS2K/PVG) and a Class 3 (LD) switch. IP traffic is routed over these trunks, converted to TDM and terminated over the PSTN.
Benefits
Applications
VoIP telephony service providers simply need to have the ability to hand off long distance VoIP calls via SIP interface to the Verizon IP network. This long distance traffic is converted to TDM within the Verizon gateway and directed to the Verizon LD network. Domestic and international termination is supported, allowing customers to take advantage of Verizons extensive network reach.
Service Level Agreements
Service level agreements (SLAs) for Carrier IP Termination are available in conjunction with the SIP Internet Access (SIA) agreement. For those customers looking for dedicated internet access, SIA is a separate product that can be provisioned to support Carrier IP Termination services. The SLAs available under the SIA agreement include Network Availability and Mean Opinion Score (MOS). (Terms and conditions apply.)
