Frontier SIP Trunking connects a business voice network with traditional or IP PBX systems and existing phone equipment. Businesses can add call paths to an existing PBX, scale usage up or down, and port current phone numbers to maintain continuity. Calling plans include blocks of long-distance minutes and telephone numbers. Frontier delivers the service over a fiber Ethernet Virtual Private Line; outside its fiber footprint, provisioning can use Frontier internet services or another provider’s internet. Frontier says its private network supports call security and call quality, while calls can be redirected to other offices or numbers during outages. Optional network redundancy is available for multiple business locations. Frontier advertises a 99.99% guaranteed circuit availability service level agreement for its Ethernet Virtual Private Network. Deployment support includes design, implementation, lifecycle management, 24/7/365 technical support, and customer-scheduled maintenance and upgrades. Pricing is customized and available on request, with packages based on the number of call paths needed. There is no free plan or trial. Service is available only in select areas, and Frontier notes that 100 Gbps internet speeds have limited availability. Frontier was founded in 1935 and is headquartered in Dallas, Texas.
