Webex: Call drops randomly and/or audio quality is bad on a WiFi network | Voice quality issues and sounds dropping in and out are due to reception issues. | 9/7/2022 | Improve WiFi reception
Voice quality issues and sounds dropping in and out are due to reception issues. Here are some remedies that can be taken, although we understand budget could be a constraint. - Move the WiFi router closer to the location of usage
- Minimize metal between the WiFi router and the location of usage (appliances, wall metal studs, furniture, etc)
- Try moving the WiFi router up (on a bookshelf for example)
- Use a different WiFi control channel if living in a congested WiFi environment like apartments (instructions)
- Try a lower Channel Bandwidth (20 MHz over 40MHz, 40MHz over 80MHz)
- If the WiFi router is dual-band, make sure 2.4Ghz and 5.0Ghz use the same SSID
- Buy a WiFi signal extender (same maker as your router works better)
- Buy a stronger WiFi router with newer standards
- A WiFi 6 (802.11ax) router would perform much better than older ones (WiFi 5, 802.11ac, 802.11n, etc) if your devices support it.
- Mesh based WiFi routers work well for larger homes with many rooms

Webex: Calls drop randomly but audio quality is good | Try installing and logging on to Global Protect before launching Webex and signing in. | 9/7/2022 | If issues still persist, - Disable DDoS protection on your router or OS
- Set TCP timeouts set to 180 seconds or larger on your router, gateway, or firewall
|
Webex: Calls drop as soon as you make or receive calls | Try installing and logging on to Global Protect before launching Webex and signing in. | 9/7/2022 | If issues still persist, Disable SIP ALG on the WiFi Router If some issues are fixed when using Global Protect, it means the WiFi Router has settings that are interfering with VoIP calls. SIP ALG being enabled is the most common of all. Here are instructions for various routers. |
Webex: Cannot make or receive calls after a successful login - "Phone Service Disconnected" error message | If you are logged in successfully but if there is an error message "Phone Service Disconnected - Sign in to your account", it means Webex can't connect to Vonage via Port 5061. This is usually a local network configuration issue that your phone / tablet / PC is using. | 9/7/2022 | Solution (PC/Mac): Try installing and logging on to Global Protect (PC/Mac) before launching Webex and signing in. If it still does not work, Windows Firewall or the Mac OS Firewall may be blocking the software or the port. Solution (Android/iPhone): Try using your cell data connection without WiFi. If it works, your WiFi or the ISP has an issue. (See Notes) Try installing and logging on to Global Protect before logging on to Webex. If it still does not work, the Webex app may not have permissions to networking or telephony in the OS app settings. If using Global Protect works but you would like to avoid using it Most likely you are on a home network with a router that's rented or purchased from your ISP. Verizon & Comcast service and routers reserve port 5061 for their own VoIP service. If you have VoIP service from your ISP, then there's no easy way around this so you will need to keep on using Global Protect. If you don't use VoIP service from your ISP, try calling your ISP and ask for all VoIP ports to be opened. If you rent or purchase your router from your ISP, it may continue blocking VoIP ports even if your ISP allows it on their server. You may need to purchase your own router to get around that. Disable SIP ALG on the WiFi Router If some issues are fixed when using Global Protect, it means the WiFi Router has settings that are interfering with VoIP calls. SIP ALG being enabled is the most common of all. Here are instructions for various routers. |
