When analyzing RTP streams, if the MAX Delta from the Provider to 3CX is lower than the reverse, where is the issue likely to be?

When analyzing RTP (Real-time Transport Protocol) streams, the MAX Delta refers to the maximum latency or delay observed in the transmission of packets. If the MAX Delta from the provider to the 3CX system is lower than the reverse direction, it indicates that packets are being transmitted more quickly from the provider to 3CX compared to the time it takes for packets to travel back from 3CX to the provider.

This scenario typically suggests that the issue lies at the provider's end because the provider is successfully transmitting the data to the 3CX system more efficiently than the 3CX system can respond back. Latency or packet loss issues typically arise when there's a bottleneck, misconfiguration, or quality of service problems in the network path leading back to the provider.

In summary, the observed asymmetry in the MAX Delta suggests that while the stream from the provider is performing adequately, the return path may be encountering delays or other issues, indicating that the root cause is likely at the provider's end.
