SIP Trunking — common questions
What is SIP trunking and how does it work?
SIP trunking links your existing PBX to the public phone network over the internet, replacing PRI or copper lines. Each channel handles one simultaneous call. Dial Raven manages connection, routing, and porting.
How much does SIP trunking cost?
Starts at $14.99/channel per month with no setup fees or long-term contracts. Industry pricing typically runs $15–$25/channel, and hidden fees elsewhere add 15–40%.
What's the difference between SIP trunking and PRI — which is cheaper?
PRI uses fixed 23-channel circuits, often $300–500/month, and scales slowly. SIP runs over the internet, adds channels instantly, and typically cuts voice costs 25–65%.
Do I need to replace my existing PBX to use SIP trunking?
No. Dial Raven connects your current PBX — Yealink, Grandstream, Mitel, Panasonic, and most major platforms — to the cloud. No forklift upgrade, no new hardware.
