Age	Commit message (Collapse)	Author	Files	Lines
2010-08-06	mgcp: Remember if the endpoint was allocated...	Holger Hans Peter Freyther	1	-0/+1
	Do not use the CI_UNUSED to decide if an endpoint is allocated but introduce a new flag. This way only the CRCX and free_endp play with the allocated field.
2010-08-06	mgcp: Make the CI uint32_t all the way to avoid mismatch	Holger Hans Peter Freyther	1	-1/+1

2010-08-06	mgcp: Add a call tap feature to forward audio to another forward port	Holger Hans Peter Freyther	1	-0/+18
	For debugging it is useful to forward (tee) UDP packets to another system and use gstreamer to inspect the rtp stream. This is untested code and might contain bugs.... and of course only tap your own calls.
2010-08-05	mgcp: Patch RTP packets again if that is allowed.openbsc/0.9.3 0.9.3	Holger Hans Peter Freyther	1	-0/+3

2010-08-05	mgcp: Allow to dynamically allocate ports from a range..	Holger Hans Peter Freyther	1	-0/+2
	Allow to switch to a dynamic port allocator and not reuse the ports for a long time... This should help with a crazy network sending two streams at the same time.
2010-08-05	mgcp: Allocate a different port for the networking...	Holger Hans Peter Freyther	1	-0/+1
	Use the right source port when sending the message.
2010-08-05	mgcp: Move the bfd for rtp/rtcp into the port	Holger Hans Peter Freyther	1	-8/+6
	Stop using the memset in the mgcp_rtp_end_reset as we will reset the list pointers and then have a mess..
2010-08-05	mgcp: Make the function internal, only used by the init/config code	Holger Hans Peter Freyther	1	-0/+1

2010-08-05	mgcp: Attempt to separate the RTP/RTCP port for the Network and for the BTS	Holger Hans Peter Freyther	1	-3/+2
	We plan to have two different ports for the network and for the BTS to avoid detecting the BTS and to dynamically allocate the port to have old data not go to a new socket.
2010-08-05	mgcp: Group the state for bts/net into a struct and have two instances	Holger Hans Peter Freyther	1	-13/+14
	Group the data that each end (network/bts) have into a struct and use this struct throughout the sourcecode.
2010-08-03	mgcp: Only patch the header if we had a change in SSRCopenbsc/0.9.1 0.9.1	Holger Hans Peter Freyther	1	-0/+1

2010-08-03	mgcp: Allow switching the audio streams, patch the header	Holger Hans Peter Freyther	1	-0/+5
	Patch the sequence number, the SSRC and the timestamp to allow to mix various voice streams, e.g. toggling the loop during the call.
2010-08-03	mgcp: Move the rtp state into a struct	Holger Hans Peter Freyther	1	-4/+8
	Use a struct to group the rtp state for the up and the down link of the bts.
2010-08-03	mgcp: Allow to change the receive (the loopback part) via the VTY	Holger Hans Peter Freyther	1	-0/+1

2010-08-03	mgcp: Implement the "loopback" mode for a connection endpoint.	Holger Hans Peter Freyther	1	-0/+9

2010-07-29	mgcp: Attempt to count missing RTP packets with a basic calculation	Holger Hans Peter Freyther	1	-0/+6
	This code compares the UDP sequence numbers of two RTP messages and guesses if packets are missing. It is guessing in two ways: 1.) by default the sequence number is 0, so on the first value we ignore the jump... we might ignore a real issue in case of a wrap around which is easily possible as the sequence should be a random number. 2.) the UDP stream might have been reordered on the network and we would see the jump... In any case these two shortcomings are acceptable for the feature that is meant to provide some basic analysis..
2010-04-25	[mgcp] Add a dummy send method...	Holger Hans Peter Freyther	1	-0/+1
	This can be used by higher level code to send one dummy message from the audio port to the network. This can be used to make the remote discover the nated port of this endpoint.
2010-04-07	[mgcp] Count incoming RTP packets from the BTS and remote	Holger Hans Peter Freyther	1	-0/+4

2010-04-05	[mgcp] Export header parsing via mgcp internal	Holger Hans Peter Freyther	1	-0/+9
	This will be used by the NAT code to implement custom protocol handling on top of that.
2010-02-26	Merge remote branch 'origin/master' into on-waves/mgcp	Holger Hans Peter Freyther	1	-1/+1
	Conflicts: openbsc/include/openbsc/Makefile.am openbsc/src/Makefile.am
2010-02-26	[mgcp] Keep track of the local and remote RTP payload type	Holger Hans Peter Freyther	1	-0/+3
	Keep track of which RTP payload type to use for which direction.
2010-02-22	[mgcp] Move away from global variables and split out VTY code	Holger Hans Peter Freyther	1	-0/+61
	In separation of using the MGCP parsing in another context, refactor the code to operate on a struct mgcp_config, split out the vty code from the mgcp_protocol.c, and move the callbacks into the mgcp code. There should be no functional changes.
