One of the frustrations of running a Tier 1 MPLS SIP trunk is the middleware problem. Your carrier delivers a premium, private-network connection, and then somewhere between their handoff and your PBX, you’re stuck deploying additional hardware — session border controllers, protocol translators, media gateways — just to make it work. The connection is enterprise-grade. The setup around it isn’t.
RingQ changes that.
The Issue with MPLS Providers & Traditional PBX
Tier 1 MPLS SIP trunk providers offer something genuinely valuable: a dedicated, labelled network path for voice traffic that never touches the public internet. Lower latency, consistent jitter, near-zero packet loss. For contact centres and high-volume environments, it’s the right infrastructure choice.
The complication has always been on the PBX side. Most systems aren’t built to natively handle a secondary network interface, which is exactly what an MPLS connection requires. So the workaround became standard practice — bolt on a piece of hardware to translate the MPLS trunk into something the PBX could digest. That’s additional cost, another point of failure, and one more device to maintain, update, and troubleshoot when calls start dropping.
It’s a workaround that has been accepted for so long it started to feel like a requirement. It isn’t.
Connect Directly with RingQ – No Translation Layer Needed
RingQ is built to support multiple network interfaces natively. That means your MPLS connection and your standard internet connection can both be active simultaneously, and RingQ knows how to route traffic across each one correctly.
For your MPLS SIP trunk, this matters in a very practical way. You configure a dedicated SIP profile bound to the MPLS interface IP, create a static route to your carrier’s SIP and RTP servers through the MPLS gateway, and set up the trunk using either registration-based or IP-based authentication — whichever your Tier 1 provider uses. That’s it. No SBC sitting in front of it. No media gateway translating protocols. No additional hardware in the chain.
The result is a direct, clean connection between your Tier 1 MPLS trunk and your RingQ platform.
Minimize Errors & Hardware
Fewer devices means fewer things to go wrong. When a call fails, you’re not debugging a translation layer — you’re looking at the trunk directly. Configuration changes made in RingQ take effect immediately without touching external hardware. And when you’re planning infrastructure, you’re not budgeting for middleware that exists only to compensate for a PBX limitation.
For IT teams managing enterprise voice environments, this simplification is significant. You get the full quality benefit of a Tier 1 MPLS trunk without the operational overhead that used to come attached to it.
