2. Mac: https://support.kixie.com/hc/en-us/articles/360012323114-Common-Microphone-Issue-with-Mac-Computers
2. Make sure your headset is fully charged, and directly connected to your computer. If possible avoid USB Hub usage as they commonly will not provide adequate power to your headset and that may cause the microphone on your headset to not properly work.

If you have administrative access to your router, then please also do the following:

1. Disable SIP ALG
2. Contact Support@kixie.com. There may be a carrier issue causing the muffled audio you experience.
