From d9400a977f7e9557c282b0ecb8ac5ef4a822e981 Mon Sep 17 00:00:00 2001 From: Harald Welte Date: Thu, 17 Aug 2017 16:31:47 +0200 Subject: mgw: Fix endpoint names for new MGW According to RFC3435, an RTP bridge forrwarding packets, transcoding or otherwise, is a single endpoint with two connections. Let's treat it as such. We introduce the "rtpbridge/" prefix to identify such special RTP endpoints.
