It can be frustrating when you can hear the person on the other end, but they can't hear you or vice versa. This blog post aims to provide an in-depth analysis of the reasons behind one-way audio issues in VoIP systems and offer practical solutions to help you resolve them effectively. Let's dive in!
Session Initiation Protocol Application Layer Gateway (SIP ALG) is a feature found in many routers and firewalls, designed to assist with VoIP traffic. While its intentions may be good, SIP ALG often causes more problems than it solves for IT professionals, particularly when working with VoIP platforms. In this blog post, we'll delve into the specifics of SIP ALG, explore which routers have it enabled by default, discuss how to disable it, and highlight the symptoms it can cause when improperly configured. We'll also cover how Viirtue's support team can help diagnose and resolve these issues.
