SIP Trunking Services for Business
If your phone bill is tied to PRI lines or rigid contracts, your communication infrastructure is costing you more than it should. Dial Raven's SIP trunking services connect your existing PBX to a reliable cloud network with HD audio, instant scalability, and full management handled by our team. Businesses that move from PRI to SIP typically cut their voice costs by 25–65% — and most Dial Raven accounts go live in under 24 hours, with no hardware changes and no downtime for their callers.
Key features
Everything you need, included and ready to use from day one.
Replace PRI Lines Without Replacing Your PBX
Your existing PBX stays in place. Dial Raven connects it to the cloud using our SIP trunk service — compatible with Yealink, Grandstream, Mitel, Panasonic, and most major PBX platforms. No forklift upgrade, no new hardware required.
Pay Only for the Channels You Use
Traditional PRI locks you into fixed 23-channel circuits at fixed costs. Our SIP trunking services are channel-based — add lines during a busy quarter, scale back when volume drops. Pricing starts at $14.99/channel with no setup fees and no long-term contracts.
99.99% Uptime With Redundant Routing
Every trunk runs through redundant routing with automatic failover. If one path goes down, calls reroute instantly — your callers never know. Backed by a 99.99% uptime SLA and 24/7 proactive monitoring that alerts us before issues reach your phones.
Crystal-Clear HD Audio on Every Call
Low-quality audio kills sales calls and frustrates customers. Our SIP trunk service delivers wideband HD audio across all connected lines — so your team sounds professional whether they're at a desk or working remotely through our mobile app.
Fully Managed — We Handle the Technical Work
Number porting, call-flow configuration, PBX compatibility checks — our US-based team handles all of it. You don't need an in-house IT team to run enterprise-grade SIP trunk services. Setup takes less than 24 hours for most accounts.
Combine SIP Trunking With AI-Powered Communication
Unlike carriers that deliver lines and disappear, Dial Raven connects your SIP trunks to a full communication stack. Add AI call transcription and summaries, smart call routing and IVR, or a virtual receptionist — all running through the same infrastructure.
Why choose Dial Raven
The advantages that make the difference, every day.
Cut Voice Costs by 25–65%
Businesses that migrate from PRI to SIP trunking typically save 25–65% on monthly telecom bills. A 23-channel PRI can cost $300–500/month; Dial Raven's channel-based pricing starts at $14.99 — so you pay for capacity you actually use, not fixed circuits.
No Hidden Fees, No Surprises
Most providers bury DID, E911, and regulatory surcharges that inflate a quote by 15–40%. Dial Raven keeps pricing transparent with no setup fees and no long-term contracts — you see the real monthly cost before you commit.
Carrier-Grade Reliability
Redundant routing, automatic failover, and 24/7 monitoring keep your calls connected even when a path fails — backed by a 99.99% uptime SLA, not a best-effort reseller network.

SIP Trunking — common questions
Quick answers about features, pricing, and setup.
What is SIP trunking and how does it work?
SIP trunking is a virtual connection that links your existing PBX to the public phone network (PSTN) over the internet, replacing physical PRI or copper lines. Each 'channel' handles one simultaneous call, so you buy only the channels you need. Dial Raven manages the connection, routing, and porting for you — no new hardware required.
How much does SIP trunking cost?
Dial Raven's SIP trunking starts at $14.99/channel per month with no setup fees and no long-term contracts. Industry pricing typically runs $15–$25/channel, and hidden fees can add 15–40% elsewhere — Dial Raven keeps pricing transparent so you see the real monthly total upfront.
What's the difference between SIP trunking and PRI — which is cheaper?
PRI uses fixed physical circuits sold in 23-channel blocks, often $300–500/month, and scales slowly. SIP trunking runs over the internet, lets you add channels instantly, and typically cuts voice costs by 25–65%. For most businesses, SIP is significantly cheaper and far more flexible.
Do I need to replace my existing PBX to use SIP trunking?
No. That's the main advantage. Dial Raven connects your current PBX — Yealink, Grandstream, Mitel, Panasonic, and most major platforms — to the cloud. There's no forklift upgrade and no new hardware; your PBX stays exactly where it is.
SIP trunking vs. hosted VoIP — which one do I need?
Choose SIP trunking if you already have a PBX you want to keep and just need modern, cheaper cloud connectivity to the phone network. Choose hosted VoIP if you'd rather replace the PBX entirely with a provider-managed cloud system. Dial Raven offers both, so we can recommend the right fit.
Can I keep my existing phone numbers?
Yes. Dial Raven ports your existing numbers — including local and toll-free — as part of onboarding, handled by our US-based team with no downtime for your callers.
How long does setup take?
Most accounts go live in under 24 hours. Our team handles number porting, PBX compatibility checks, and call-flow configuration — so there's no downtime and no in-house IT work required.
