SIP Trunking Services

VoIP refers to the general technology used to transmit voice over the internet. High-volume SIP providers use SIP trunking as the specific method to connect a PBX to the public telephone network. While VoIP is the broad category, SIP trunking serves as the digital replacement for traditional phone lines, facilitating ISDN/PRI to SIP migration for modern businesses.

High-volume SIP providers deliver carrier-grade voice that scales to meet demanding traffic needs. CommPeak provides elastic SIP trunking so you can adjust concurrent call capacity on demand. Our tier 1 SIP trunking operates low-latency global routing through 10 strategic PoPs to ensure professional audio quality and high uptime. CommPeak infrastructure supports demanding traffic volumes while maintaining a 99.999% uptime SLA.

CommPeak secures your voice environment with geo-redundant Infrastructure and advanced authentication methods like JWT authentication. You can set call blocking rules to prevent unauthorized activity and use rate capping to manage budgets. Our proactive monitoring tools provide the visibility you need to identify suspicious patterns, while critical alerts and SIP error logs help you catch and address configuration issues early.

Network monitor (pinger) provides real-time visibility to help you identify jitter or packet loss. Use SIP call analysis to pull signaling data and SIP error logs to find the root cause of performance gaps. To prevent service disruption during network issues, auto failover switches traffic to backup carriers.

One-way audio often occurs when voice packets cannot pass through a firewall or router properly. CommPeak uses NAT traversal to fix these signaling issues, establishing stable two-way communication. NAT traversal also bypasses network configuration errors to deliver clear audio.
