SoundLine puts your complete business phone system in your pocket. Make and receive calls using your business numbers, send and receive SMS and MMS messages, and collaborate with your team — all from
your personal device.

BUSINESS CALLING
Place calls through your business phone numbers with proper caller ID. See who's calling before you answer with inbound call notifications. Review your complete call history with details like duration,
routing, and missed calls.

SMS & MMS MESSAGING
Send and receive text messages using your business numbers — keep your personal number private. Share photos and images via MMS. Manage conversations across multiple phone numbers with clear "via"
labels so you always know which line you're on.

MULTIPLE NUMBERS & ACCOUNTS
Manage multiple business phone numbers (DIDs) from a single app. Business owners with multiple accounts can switch between them seamlessly and see activity across all accounts at a glance.

TEAM COLLABORATION
Stay connected with your team through built-in channels and direct messages. Share updates, coordinate responses, and keep your business communication organized in one place.

CONTACTS
Access both your business contacts and personal contacts side by side. Tap to call or message any contact using the right business number.

REAL-TIME NOTIFICATIONS
Get instant push notifications for incoming texts and calls. Never miss a customer message or an important call, even when the app is in the background.

SECURE SIGN-IN
Sign in securely with single sign-on (SSO). Your credentials are protected with industry-standard authentication.

SoundLine is designed for businesses that use the SoundLine Communications phone system. A SoundLine account is required.
