Direct dial is routing. A direct dial can be an office line or a VoIP endpoint, and treating it like a mobile channel can create compliance and candidate-experience issues.<\/p>\n<\/li>\n<li>\n<p><strong>Not tracking recency.<\/strong> Numbers get reassigned when clinicians change groups or clinics update phone systems. If you don\u2019t store \u201clast verified,\u201d you can\u2019t tell whether you\u2019re dialing a current endpoint or a recycled line.<\/p>\n<\/li>\n<li>\n<p><strong>Calling the same failed route repeatedly.<\/strong> If you hit an IVR twice, stop. Switch to a routing ask (operator\/front desk) or email to request the best path.<\/p>\n<\/li>\n<li>\n<p><strong>Not documenting the successful path.<\/strong> When you do get through, capture the extension, IVR path, and best time window. That\u2019s how you reduce wasted dials across the team.<\/p>\n<\/li>\n<li>\n<p><strong>Opt-out leakage.<\/strong> If someone asks you to stop, suppress the number and channel. Don\u2019t let another sequence hit them next week.<\/p>\n<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"How_to_improve_results\"><\/span>How to improve results<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Improvement comes from routing discipline: fewer dials into phone trees, more attempts on verified endpoints, and better documentation.
