SIP Trunks

SIP (Session Initiation Protocol) is the industry-standard technology used to convert voice calls into data. SIP trunks allow your existing PABX or phone system to make VoIP calls using your current internet connection. No separate phone lines required.

How SIP Trunks Work

SIP is the protocol that enables VoIP, allowing voice to travel over data networks. Your SIP services can be delivered over the network you already have, or we can build a private data solution that’s tailored specifically to your business. It’s a flexible, cost-effective way to make and receive calls on your current PABX without extra hardware or dedicated phone lines.

Why Businesses Choose SIP Trunks

Lower Costs

Save on line rental, hardware, and call charges. Add channels as needed and enjoy fixed monthly fees that keep budgeting simple.

Easy to Scale

Add or remove channels instantly, support remote teams, and connect all your sites under one system. You can keep your existing numbers even if you move.

More Reliable

Built-in redundancy (like automatic failover to a mobile service) keeps your business reachable during outages. SIP also supports clearer, higher-quality calls.
