1. Choppy Voice Audio

Choppy audio refers to audio that cuts in and out, making it difficult to understand the speaker. This can be due to various reasons:

Causes & Solutions:

a. Network Congestion:

Symptom: Other network activities, like file downloads, streaming, or large data transfers, might cause the voice to chop.

Solution: Prioritize voice traffic using Quality of Service (QoS) settings on your router or network switch.

b. Insufficient Bandwidth:

Symptom: Regularly experiencing choppy voice during peak business hours.

Solution: Upgrade your internet package or consider a dedicated line for voice traffic.

c. Wireless Interference:

Symptom: The issue occurs predominantly when using wireless phones or headsets.

Solution: Change the Wi-Fi channel on your router or switch to a wired connection.

2. One-Way Audio

One-way audio is when one party can hear the other, but the other party cannot hear in return.

Causes & Solutions:

a. NAT (Network Address Translation) Issues:

Symptom: Frequently occurs when phones are behind routers.

Solution: Disable SIP ALG if your router supports it. (Guide )

b. Firewall Restrictions:

Symptom: Calls from specific numbers or services result in one-way audio.

Solution: Adjust firewall settings to allow voice traffic.

c. Muted Microphone:

Symptom: Simple but often overlooked - one party has their microphone muted.

Solution: Check the mute button on the phone, software, or headset.

d. Hardware Issues:

Symptom: One-way audio persists even after changing handsets or headphones.

Solution: Check for malfunctioning equipment, like cables, curly cords, phones, or headsets. Replace if necessary.
