Using a VPN (Virtual Private Network) may cause issues when using the Convoso system.

In VoIP, timeliness is more important than Packet Loss. Losing a few frames is a small issue, on the other hand, Packets arriving later or rubber-banding have been seen to cause massive audio issues.

Real-time voice protocols use UDP (User Datagram Protocol) which ignores queuing or retrying.

If you layer your UDP communication on top of a VPN:

• A UDP VPN may introduce some Latency.
• A TCP (Transmission Control Protocol) VPN can cancel out the benefits of UDP.

Using a Zero Trust Network Access (ZTNA) tool such as a ZScaler, or other ZTNA or VPN-adjacent tool can cause latency issues and introduce routing concerns that may impact connectivity.

These tools can cause issues such as disconnects, call drops, and one-sided audio. 

Please reach out to our support team for guidance on the necessary whitelists for your VPN Policies.

Please refer to Convoso's Technical Specifications for requirements and recommendations for using the Convoso system.
