Jacob Erlbeck 58340e5b5b mgcp/rtp: Fix RTP timestamps if enabled
This forces the output timing to fulfill
   dTS = dSegNo * fixedPacketDuration
where dSegNo = seqNo - lastSeqNo.

If timestamp patching is enabled, the output timestamp will be set
to lastTimestamp + dTS. This kind of relative updating is used to
handle seqNo- and timestamp-wraparounds properly.

The updating of timestamp and SSRC has been separated and the patch
field of mgcp_rtp_state has been renamed to patch_ssrc to reflect
it's semantics more closely. The offset fields are now used always
and will change the corresponding header field if they are != 0.

About OpenBSC
=============

OpenBSC is a minimalistic implementation of the GSM Network, with
particular emphasis on the functionality typically provided by the BSC,
MSC, HLR, VLR and SMSC.

Its currently supported interfaces towards the BTS are:

 * Classic A-bis over E1 using a mISDN based E1 interface. In other
   words, you can connect existing GSM Base Transceiver Station (BTS)
   through E1 to OpenBSC.  So far, we have only tested the Siemens BS-11
   Test reports with other BTS are much appreciated!

 * A-bis over IP as used by the ip.access nanoBTS product family

You can find the project documentation at http://openbsc.gnumonks.org/

This project is still in its early days, and there are lots of areas where it
doesn't behave as per GSM spec.

libosmocore
===========

Please note that as of March 2010, OpenBSC has a dependency to a library
called "libosmocore".  You can obtain that library from

	git://git.osmocom.org/libosmocore.git
