Volli Communications uses redundant SIP switches and dispersed RTP Proxy clusters to ensure clear voice and data relays without latency or jitter. Customers can send outbound data via two data centers, using their preferred method for uptime assurance. Inbound data can be delivered similarly. Clients can register with Volli’s BGP-controlled IPs for smooth failover without delays. Supported by top carriers, Volli offers phone numbers in every North American rate center.
