2017-08-27	move openbsc/* to repos root	Neels Hofmeyr	1	-43/+0
	This is the first step in creating this repository from the legacy openbsc.git. Like all other Osmocom repositories, keep the autoconf and automake files in the repository root. openbsc.git has been the sole exception, which ends now. Change-Id: I9c6f2a448d9cb1cc088cf1cf6918b69d7e69b4e7

2015-08-14	mgcp: Move the SDP handling into a separate file/module	Holger Hans Peter Freyther	1	-1/+2
	The SDP file handling will get more complicated in terms of codec selection so let's remove it from the protocol handling before we start blowing it up in size.
2014-08-28	osmux: rename osmux.c to mgcp_osmux.c	Pablo Neira Ayuso	1	-1/+1
	So we can easily identify in the log message what refers to libosmo-netif and what to libmgcp.
2014-06-05	mgcp: Move transcoding to libmgcp	Jacob Erlbeck	1	-3/+9
	This patch moves the files relevant to transcoding from src/osmo-bsc_mgcp to src/libmgcp and src/include/openbsc. Makefiles and include directives are being updated accordingly. Sponsored-by: On-Waves ehf
2014-05-22	mgcp: add voice muxer support	Pablo Neira Ayuso	1	-3/+5
	This patch adds the voice muxer. You can use this to batch RTP traffic to reduce bandwidth comsuption. Basically, osmux transforms RTP flows to a compact batch format, that is later on decompacted to its original form. Port UDP/1984 is used for the muxer traffic between osmo-bsc_nat and osmo-bsc_mgcp (in the BSC side). This feature depends on libosmo-netif, which contains the osmux core support. Osmux is requested on-demand via the MGCP CRCX/MDCX messages (using the vendor-specific extension X-Osmux: on) coming from the BSC-NAT, so you can selectively enable osmux per BSC from one the bsc-nat.cfg file, so we have a centralized point to enable/disable osmux. First thing you need to do is to accept requests to use Osmux, this can be done from VTY interface of osmo-bsc_nat and osmo-bsc_mgcp by adding the following line: mgcp ... osmux on osmux batch-factor 4 This just initializes the osmux engine. You still have to specify what BSC uses osmux from osmo-bsc_nat configuration file: ... bsc 1 osmux on bsc 2 ... bsc 3 osmux on In this case, bsc 1 and 3 should use osmux if possible, bsc 2 does not have osmux enabled. Thus, you can selectively enable osmux depending on the BSC, and we have a centralized point for configuration from the bsc-nat to enable osmux on demand, as suggested by Holger. At this moment, this patch contains heavy debug logging for each RTP packet that can be removed later to save cycles. The RTP ssrc/seqnum/timestamp is randomly allocated for each MDCX that is received to configure an endpoint.
2013-06-12	Makefile.am: Use AM_CPPFLAGS	Alexander Huemer	1	-1/+1
	Since automake 1.13 INCLUDES is depricates and causes a warning
2011-03-23	src: use new library libosmogsm and new path to headers in libosmocore	Pablo Neira Ayuso	1	-1/+1
	libosmogsm is a new library that is distributed in the libosmocore. Now, openbsc depends on it. This patch gets openbsc with this change. This patch also rewrites all include path to the new osmocom/[gsm\|core] Signed-off-by: Pablo Neira Ayuso <pablo@gnumonks.org>
2011-03-04	prefix sub-directories containing libraries with 'lib'	Harald Welte	1	-0/+7
	... and make sure tests work again after restructuring
