4Voice’s 2Link is an affordable SIP VoIP solution that saves you money and improves reliability by using your existing telephone system's Voice-over-IP (VoIP) interfaces.
In contrast to traditional trunking, our SIP trunks are burstable so callers can get through even during peak capacity. You no longer need to over-engineer your trunks just to account for a small set of high volume days. In addition, 2Link VoIP service does not require a separate trunk resource for toll-free or outbound calls, saving you money over traditional telephony solutions.
The 2Link VoIP service provides SIP-based interconnection to your existing VoIP-capable telephone system. This service allows you to connect to the telephone network, or between locations, using a single data infrastructure (no need for PRIs or analog lines). You can save by streamlining your network and taking advantage of lower rates for long-distance and toll-free calls.
For businesses with multiple locations, 2Link eliminates complex and costly inter-office calling infrastructure and allows for more flexible routing of incoming calls across locations.
