In fact, you can choose from predefined voicemail messages and send blocked callers directly there\u2014just as if you simply didn\u2019t answer.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Adding numbers to the block list can be done directly\u00a0 from users\u2019 RingCentral apps.

But spam calls can completely interrupt their focus and time, which can be better spent on serving real customers.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">In addition, if you have agents assigned to serve a specific area code, you can configure block settings so they only receive calls from that area code and automatically send all others to voicemail. This ensures that only relevant calls reach their phones, helping hit targets faster.<\/span><\/p>\n<h3>2. It helps you stay focused<\/h3>\n<p><span style=\"font-weight: 400;\">Imagine that you\u2019re working on an urgent, heads-down project and need total concentration for several days in a row.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">With advanced call blocking, you can create your own \u201cdo not disturb\u201d mode by blocking all non-important numbers. If you\u2019re expecting important calls, simply adjust your block settings to allow specific numbers to come through.<\/span><\/p>\n<h3 class=\"heading h3\">3. It can reduce call queues<\/h3>\n<p><span style=\"font-weight: 400;\">It\u2019s simple \u2014if your business isn\u2019t being bombarded with spam calls, and your agents and reps don\u2019t have to waste their time on answering them, your phone lines won\u2019t be tied up when genuine customers and prospects are trying to reach you.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">That means a reduction in wait times, which improves the customer experience as well as increasing efficiency.<\/span><\/p>\n<div class=\"download-form-widget download-cta-banner \" data-url=\"https:\/\/assets.ringcentral.com\/us\/whitepaper\/elevating-productivity-genai.pdf\" data-id=\"6a3f90600086f\" id=\"6a3f90600086f\" data-form-type=\"cta download banner SMB\">\n<div class=\"rc-post-content-cta rc-post-content-cta_download green\">\n<div class=\"img-rc-cta-download\">\n\t\t\t\t<svg width=\"290\" height=\"234\"  fill=\"none\" id=\"svg--580530831\" role=\"img\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\">\n\t\t\t\t<path d=\"M213.846 96.959C222.779 130.299 257.048 150.084 290.388 141.15C323.728 132.217 343.513 97.9482 334.579 64.6087C325.646 31.2691 291.377 11.4839 258.038 20.4173L203.159 35.122C200.128 35.9341 198.329 39.0494 199.141 42.0803L213.846 96.959Z\" fill=\"#FF7A00\"\/>\n\t\t\t\t<path d=\"M153.092 88.4508C154.825 86.7179 154.825 83.9299 153.092 82.1969L81.1733 10.2785C79.4405 8.54566 76.6392 8.55885 74.9846 10.3437C35.9115 52.6218 35.9115 118.026 74.9846 160.304C76.6394 162.089 79.4535 162.089 81.1733 160.369L153.092 88.4508Z\" fill=\"#0684BC\"\/>\n\t\t\t\t<path d=\"M116.67 194.759L102.313 219.626C101.621 220.825 102.029 222.345 103.227 223.037L128.095 237.394C143.024 246.014 162.11 240.9 170.73 225.97C179.349 211.041 174.235 191.954 159.306 183.335C144.376 174.716 125.29 179.83 116.67 194.759Z\" fill=\"#FFCD00\"\/>\n\t\t\t\t<path d=\"M184.513 4.20398C184.94 5.7996 183.997 7.43423 182.401 7.86177L134.082 20.8089C132.486 21.2364 130.852 20.2926 130.424 18.697L117.477 -29.6222C117.049 -31.2178 117.993 -32.8524 119.589 -33.2799L167.908 -46.227C169.504 -46.6545 171.138 -45.7109 171.566 -44.1152L184.513 4.20398Z\" fill=\"#F6F5F1\"\/>\n\t\t\t\t<path d=\"M195.505 160.14C195.025 160.972 193.966 161.256 193.135 160.776L167.963 146.242C167.131 145.763 166.848 144.703 167.327 143.872L181.861 118.7C182.341 117.869 183.4 117.585 184.231 118.065L209.403 132.598C210.235 133.078 210.518 134.137 210.038 134.968L195.505 160.14Z\" fill=\"#205C40\"\/>\n\t\t\t\t<\/svg>\t\t\t<\/div>\n<div class=\"rc-content-cta-download\">\n<div class=\"bottom-cta-copy\">\n<div class=\"title-banner-cta-download\">IT Guide to Generative AI in Business Communication<\/div>\n<div class=\"text-banner-cta-download\">Discover how generative AI can elevate productivity and transform business communications <\/div>\n<\/p><\/div>\n<\/p><\/div>\n<div class=\"rc-post-content-cta-footer\">\n\t\t\t\t<button tabindex=\"on\" on=\"tap:6a3f90600086f.toggleClass(class='open')\" class=\"open-modal-download-action rc-button\" type=\"submit\">Get the eBook<\/button>\n\t\t\t<\/div>\n<\/p><\/div>\n<div class=\"download-form-modal\">\n<div class=\"download-form-modal-body\">\n<div class=\"download-form-modal-content\">\n<div class=\"download-form-modal-title\"> AI is revolutionizing productivity and enhancing business communication.
