## What is SoundLine Mobile?

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, direct messages, and video conferencing. Share updates, coordinate responses, and keep your business communication organized in one place.

 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.
