Phone Call Icon with Signal Waves

This is a clear, line-art icon showing a classic telephone receiver paired with three curved lines, which universally symbolize outgoing sound or signal waves. The design is clean and minimalist, commonly used to represent making a phone call, customer support, contact information, or active audio communication. It's ideal for user interfaces, websites, or any visual content needing a straightforward call-to-action or communication symbol.
