From ee11bc0f5c69d8ffa78b5de1de0ec365e4de4a12 Mon Sep 17 00:00:00 2001 From: Pablo Neira Ayuso Date: Wed, 17 Sep 2014 12:33:09 +0200 Subject: osmux: send osmux stats in MGCP DLCX responses This allows us to know what number of messages and bytes has been received per active osmux endpoint. Note that an Osmux message is composed of several chunks. Each chunk contains an osmux header plus several voice data frames.
