freetdm: improved logic to enable/disable EC on call start/stop - MFC-R2 requires tone signaling that gets screwed sometimes if the EC is enabled during call setup. - EC is now enabled only when switching to a state requiring media (UP and PROGRESS_MEDIA) - The logic is aware of EC persist option in Wanpipe - Improved logging in ftmod_wanpipe to print EC state on startup
