An inbuilt multi-view switchboard allows users to manage incoming calls, view all colleague availability, and drag-and-drop calls for transfer. With CRM integration, users can launch calls in a single click from within their CRM software, and customer information appears as a pop-up on inbound calls. Caller ID is used to identify customers and automatically log the call in their customer record, with no need for manual call logging. \n\n3CX’s smartphone clients for Android and iOS allow users to make and receive calls over 3G or WiFi, and each include an inbuilt SIP tunnel to prevent issues with remote firewalls. Incoming calls and messages trigger push notifications, allowing phones to be left on standby to reduce battery drain. Users can update their availability statuses through the app, and view their colleagues’ statuses. Through 3CX’s mobile apps, users can make and receive calls from their mobile phone without the need to give out their personal phone number. \n\n3CX offers users clientless web conferencing, with no need to download additional software or plugins, as all voice and video communication is based in a web browser.  Also included are tools for remote control and assistance, and for feedback collection.","image":"https://gdm-catalog-fmapi-prod.imgix.net/ProductScreenshot/a45b818e-d95e-4051-9610-8554ae518554.webp","url":"https://www.getapp.co.uk/software/103409/3cx","@type":"SoftwareApplication","@id":"https://www.getapp.co.uk/software/103409/3cx#software","applicationCategory":"BusinessApplication","publisher":{"@id":"https://www.getapp.co.uk/#organization"},"aggregateRating":{"@type":"AggregateRating","bestRating":5,"ratingCount":465,"ratingValue":4.4},"offers":{"price":"350","@type":"Offer","priceCurrency":"GBP"},"operatingSystem":"Cloud, Apple, Windows, Linux, Windows on premise, Linux on premise, Android, Platform ios, Platform ipad"},{"name":"Rainbow","description":"Rainbow is a sovereign hybrid collaboration platform from the cloud for businesses of all sizes.
