@AscendLLC  OP here on a new account bc I got locked out of my previous cisco sso ID 😄    Need more info to help you: 1. What exactly is the problem you are having? No audio on inbound voip calls? Or just poor quality? 2. Who is your hosted voip carrier?   If it's poor quality, there's not much reason it would only impact inbound calls.   If it's one way audio or no audio then you may want to contact Meraki Go support to find out if there's a way to "trigger" or "open" some specific TCP & UDP ports which your voip carrier would need to tell you. Most common ones for voip are UDP 5060-5090. To my knowledge, the GX20 doesn't have a "SIP ALG" feature which some small biz/home routers have that interferes with cloud voip calling.   We have an MGO GX20 and MGO switches powering our office network with 9 voip endpoints on a 150mbps cable connection with no quality issues. Typically 3-4 users on calls max at a time. No special QOS or port triggering was required. We're using Webex Cloud Calling and 8800 series cisco phones. In evaluation before install, we also tried Zoom Phone voip, and no issues with that either. ... View more
