Most businesses need more than a dial tone. Whether you’re calling a client in the next town or coordinating a team across three continents, communication should be seamless, secure, and above all…simple.

Wildix CLASSOUND, is a built-in SIP trunking service that handles both local and global traffic without the usual carrier complications. It’s not an add-on or a bolt-on. It’s a core part of your Wildix environment from day one.

Calling locally or worldwide? Wildix CLASSOUND keeps you connected.

A calling app is only as good as the network behind it. When your business needs to sound clear, professional, and reliable, whether you’re dialling across town or across the world, you need more than a basic trunk. You need one that’s built in, built for scale, and built to just work.

This is the difference an embedded global carrier makes.

Why traditional SIP Trunks can become a headache

Many organisations move to SIP expecting simplicity, only to discover it often delivers the opposite.

Coverage gaps: Most SIP trunks are region-specific. The moment you expand internationally, you’re suddenly managing extra carriers, extra contracts, and extra support portals. The admin grows faster than the business.
Support ping-pong: When something goes wrong, responsibility becomes a moving target. The PBX provider points to the carrier, the carrier points back to the PBX, and your team ends up playing referee instead of resolving the issue.
Unpredictable billing: Per-minute charging, international surcharges, and carrier-specific fees make monthly invoices feel more like a surprise than a forecast.
Technical friction: Setting up or porting international numbers can involve long lead times and complex coordination increasing the risk of downtime during migration.
Limited resilience: Not every SIP provider offers global failover or guaranteed HD voice quality. Reliability becomes a postcode lottery.

How CLASSOUND fixes the experience

Because CLASSOUND is embedded directly into the Wildix ecosystem, the middleman disappears. Your phone system and your dial tone become one unified platform – managed, supported, and delivered through Evoke.
