-rtp-gsmfr-extr	This program focuses on a single selected RTP stream like the

-		then further enforces that every RTP packet be one of these 3
-		possibilities: a GSM FR1 codec frame, a GSM EFR codec frame or
-		a Themyscira BFI marker as defined in the RTP-BFI-extension
-		document.  (The payload type number is NOT considered, only the
-		payload length and the characteristic signature of each of the

-		playable WAV with gsmfr-decode or gsmefr-decode.
+rtp-gsmfr-dump	This program focuses on a single selected RTP stream like the
