Resolved Issues

This release contains the following resolved issues:

On Windows, Google STT/TTS resource can now have port 443 specified in the resource URI of its Resource Access Point in order for MCP to cooperate with the proxy that needs a port presented explicitly. (GVP-43939)

MCP now handles SDP capability negotiation in re-INVITEs correctly. Previously, MCP did not do so, resulting in extra m-lines in the 200 OK answer.

MCP does not support ICE when SDP capability negotiation is involved.


MCP now properly records RTP streams with various ptime using Opus format. Previously, Opus recording was broken if ptime of the RTP stream was not 20ms. (GVP-43688)

MCP no longer shuts down unexpectedly if the MRCPv2 server sends back the SIP re-INVITE to MCP. (GVP-43651)

The RTP timestamp after a DTMF event from a conference now has the event duration extended. (GVP-43466)
