Configuring SBC for Kandy Link

In this section:

Overview

In cases where the SBC is positioned between Kandy Link and Ribbon AS/Cisco UCM, the following SMM rules should be considered. Ribbon Professional Services should be involved in applying these rules.

Use the following CLI syntax to configure a SIP Adaptor Profile for passing x-webrtc and x-p2p parameters.

Configuring a SIP Adaptor Profile for Passing x-webrtc and x-p2p Parameters – Input SMM Profile

This rule should be applied as the Input SMM Profile for both the trunk groups facing Kandy Link and the AS/CiscoUCM.

Max MTU Size

Due to double audio and video mline, sdp size is too LARGE. The Max MTU Supported Over UDP Value must be 5,000.
