What's New

Introduces RTP port reservation for outbound calls and updates DTLS-SRTP to use ECDSA P-256 certificates.

Breaking Changes

DTLS-SRTP deployments using RSA-2048 certificates will break with peers that only support RSA key exchange.

New Features

RTP port reservation for outbound calls via `[media].reserved_outbound_calls` config.
DTLS-SRTP ECDSA P-256 support.
New metrics for RTP reserve blocks and reserved outbound calls.

Improvements

Exact floor reservation logic evaluated inside the RTP pool allocator's critical section for better concurrency.
forge-media pinned to a specific commit for the new allocator functionality.

Upgrade Notes

Upgrading changes nothing until you set `[media].reserved_outbound_calls` to a non-zero value. DTLS-SRTP deployments must ensure peers support ECDSA P-256 or the connection will fail. A restart is required for configuration changes to take effect.
