This is an automated email from the git hooks/post-receive script. It was generated because a ref change was pushed to the repository containing the project "The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)".

That is to say, the old revision is not a strict subset of the new revision. This situation occurs when you --force push a change and generate a repository containing something like this: * -- * -- B -- O -- O -- O (f7637bc5155e14aabdcae1d3271a43ebbade6ef8) \ N -- N -- N (5724fb76169008c7f7d6bf8ffedbe2a4a78f8e00) When this happens we assume that you've already had alert emails for all of the O revisions, and so we here report only the revisions in the N branch from the common base, B. Those revisions listed above that are new to this repository have not appeared on any other notification email; so we list those revisions in full, below. - Log ----------------------------------------------------------------- http://cgit.osmocom.org/openbsc/commit/?id=5724fb76169008c7f7d6bf8ffedbe2a4… commit 5724fb76169008c7f7d6bf8ffedbe2a4a78f8e00 Author: Andreas Eversberg <jolly(a)eversberg.eu> Date: Sun Mar 31 12:01:25 2013 +0200 osmo-nitb support for codec negotiation The caller's most preferred codec is selected out of the union of codecs, which both parties support.

This patch drops these frames. It depends on the other RTP endpoint how dropped frames are handled.

The amount of incrmentation is calculated from the elapsed time. Not incrementing timestamp and sequence number would cause all frames to be dropped by ipaccess BTS, because the BTS expects frames with more recent timestamps. If speech frames are received too fast, they must be dropped. The timestamp and sequence number of the RTP socket state are not changed in this case. Incmenetating timestamp and sequence number would causes high delay at ipaccess BTS, because the BTS would queue the frames until the timestamp matches the current time. There is a simple test case: Make a call between two phones and check the delay. (When using LCR, make a call to the echo test.) The press CTRL+z to suspend OpenBSC process for a few seconds and enter "fg" to continue OpenBSC process. There shall be no change in the delay, even after repeating this test many times. http://cgit.osmocom.org/openbsc/commit/?id=fa032ac8b3c1f49c908dcd5380b48f19… commit fa032ac8b3c1f49c908dcd5380b48f198439494e Author: Andreas Eversberg <jolly(a)eversberg.eu> Date: Fri Feb 17 15:20:59 2012 +0100 Allow dynamic RTP payload types between application and MNCC interface Since EFR/AMR/HR codecs use dynamic RTP payload, the payload type can be set. If it is set, the frame type must be set also, so OpenBSC knows what frame types are received via RTP. This modification only affects traffic beween application and MNCC interface, not the RTP traffic between OpenBSC and BTS. http://cgit.osmocom.org/openbsc/commit/?id=990b41308770426eec50cbee6ac5f270… commit 990b41308770426eec50cbee6ac5f270f93afee2 Author: Andreas Eversberg <jolly(a)eversberg.eu> Date: Mon Jan 16 09:29:28 2012 +0100 Add traffic forwarding via RTP to remote application Instead of forwarding traffic through MNCC interface, traffic can be forwarded to a given RTP peer directly. A special MNCC message is used to control the peer's destination. The traffic can still be forwarded through MNCC interface when this special MNCC message is not used. It also works with E1 based BTSs. In conjunction with LCR's "rtp-bridge" feature, the RTP traffic can be directly exchanged with a remote SIP endpoint, so that the traffic is not forwarded by LCR itself. This way the performance of handling traffic only depends on OpenBSC and the remote SIP endpoint. Also the traffic is exchanged with the SIP endpoint without transcoding, to have maximum performance. Increment MNCC version to 5. ----------------------------------------------------------------------- Summary of changes: openbsc/include/openbsc/gsm_data_shared.h | 1 - openbsc/include/openbsc/mncc_int.h | 2 - openbsc/include/openbsc/rtp_proxy.h | 4 +- openbsc/include/openbsc/transaction.h | 2 +- openbsc/src/libbsc/abis_rsl.c | 59 +++++++-------- openbsc/src/libbsc/bsc_vty.c | 25 ------- openbsc/src/libbsc/bts_nokia_site.c | 1 - openbsc/src/libmsc/gsm_04_08.c | 104 ++------------------------ openbsc/src/libmsc/mncc_builtin.c | 17 ++--- openbsc/src/libmsc/mncc_sock.c | 8 +- openbsc/src/libmsc/vty_interface_layer3.c | 36 --------- openbsc/src/libtrau/rtp_proxy.c | 117 +++++++++++++++--------------- openbsc/tests/gbproxy/gbproxy_test.c | 3 +- 13 files changed, 107 insertions(+), 272 deletions(-) hooks/post-receive -- The OpenBSC GSM Base Station Controller (+MSC/HLR/SGSN)
