Here are some best practices in this regard.<\/p><ul><li>Implement strong passwords: Replace default passwords with complex passphrases combining upper and lowercase letters, numbers and symbols.<\/li><li>Update VoIP software regularly: Set up automatic updates for all VoIP devices and regularly check with your VoIP provider for firmware updates.<\/li><li>Enable firewalls and network segmentation: Configure VoIP-specific firewalls to monitor SIP traffic and set up network segmentation to isolate sensitive data.<\/li><li>Deploy VoIP monitoring tools: Use tools like SolarWinds and Wireshark to identify latency, jitter and unauthorised activity. Also, set alerts for suspicious login attempts or traffic spikes.<\/li><li>Train employees: Educate staff on phishing attacks and suspicious calls, along with encouraging them to report unusual activity immediately.<\/li><li>Choose a VoIP provider that prioritises security protocols: Choose a provider that offers in-built encryption, DDoS protection and proactive security monitoring.<\/li><\/ul>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<section class=\"elementor-section elementor-top-section elementor-element elementor-element-37b0cc8 elementor-section-boxed elementor-section-height-default elementor-section-height-default\" data-id=\"37b0cc8\" data-element_type=\"section\" data-settings=\"{&quot;_ha_eqh_enable&quot;:false}\">\n\t\t\t\t\t\t<div class=\"elementor-container elementor-column-gap-default\">\n\t\t\t\t\t<div class=\"elementor-column elementor-col-100 elementor-top-column elementor-element elementor-element-dc9a687\" data-id=\"dc9a687\" data-element_type=\"column\">\n\t\t\t<div class=\"elementor-widget-wrap elementor-element-populated\">\n\t\t\t\t\t\t<div class=\"elementor-element elementor-element-8f6282c elementor-widget elementor-widget-heading\" data-id=\"8f6282c\" data-element_type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t<h2 class=\"elementor-heading-title elementor-size-default\"><span class=\"ez-toc-section\" id=\"set_up_a_secure_voip_system_for_your_business_with_comparedbusiness\"><\/span>Set Up A Secure VoIP System For Your Business With ComparedBusiness<span class=\"ez-toc-section-end\"><\/span><\/h2>\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-7383b84 elementor-widget elementor-widget-text-editor\" data-id=\"7383b84\" data-element_type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t<p>A secure VoIP system should be encrypted, updated and monitored regularly.
