SBC call flows consisting of SIP or H.323 on one leg and Gateway on the other exhibit the same performance and capacity metrics as pure SIP or H.323 calls.
Modified: for 9.2.4
The SBC is enhanced with the addition of three gateway-specific signaling flags in the SIP trunk group signaling configuration to support the handling of 100rel-based back-to-back 18x responses using SDP changes to block irrelevant Re-INVITE/UPDATE messages between gateways. This configuration will prevent potential one-way audio issues between gateways.disableMediaLockDownAtGwSg
