E-SBC: One-way audio for IPv6 end points (Doc ID 2937200.1)

Last updated on AUGUST 27, 2024

Applies to:

Net-Net OS - Version S-Cz8.3.0 to S-Cz9.1.0 [Release S-Cz8.0 to S-Cz9.1]
Information in this document applies to any platform.

Symptoms

One way audio (OWA) is observed for IPv6 end points on 3900, 1100 and 4900 platforms

Changes

The parameter rtcp-policy was set on the corresponding realms associated with the IPv6 end points.
When rtcp-policy is set, transcoding is triggered (even if the codecs on both ingress and egress side are the same). RTCP generation requires DSP resources.

The issue doesn't affect the IPv4 end points with rtcp-policy set
