Andreas Eversberg f6aea744f8 Removed complete bchannel handling from chan_lcr 
The remote application interface does not allow any bchannel to be
exported or imported. Audio traffic via socket interface is used instead.

The joinremote instance became obsolete and is removed.

The remote action (routing) became obsolete, use interface.conf instead.

The handling of loopback device became obsolete and was removed

The chan_lcr does not rely on mISDN anymore, that means:
- can be used with GSM and without mISDN at all.
- chan_lcr can be used as internal extension of LCR (e.g. SIP phone)
  (chan_lcr can be handled as any other interface)
- no loopback device to be used anymore.

Andreas Eversberg 67e162715d Adding TX-dejitter feature for briged data to mISDN 
In case there is data bridged to an mISDN port, the TX-dejitter feature
is enabled in the kernel, to keep the delay at a minimum.

Andreas Eversberg 5463e1b62a Added bridgin support for GSM and SIP 
The dependency on mISDN (loopback interface) is completely removed
from GSM and SIP interfaces.

The built in bridge of LCR now forwards audio data between these
interface instances or between these instances and other instances.

Additionally both GSM BS and SIP support direct forwarding of RTP
traffic between  other SIP endpoint and OpenBSC, so no traffic is
forwarded by the LCR itself. This is done by forwarding RTP peer
informations between these interface instances.

Andreas Eversberg 877a2dfd52 Adding bridge between protocol handlers (ports) 
This is required to bridge traffic beween non-mISDN handlers,
such as GSM, SIP and voice box. Also it bridges traffic between
mISDN handlers and non-mISDN handlers. It is the fundamental step
to get rid of mISDN (loop interface) for non-mISDN handlers.
This is required to bridge audio e.g. between SIP and GSM without
using mISDN. There will be no limitations on 'b-channels' anymore.

Still GSM and SIP requires mISDN, but this will be changed later.

With that bridge I cleaned up some code and also removed the
MESSAGE_DATA, which is not required anymore.

Andreas Eversberg 863bc64219 Adding basic SIP support, using Sofia-SIP stack 
This support is just a simple peer-to-peer support for basic calls.

Currently it requires mISDN_l1loop interface, as every non-ISDN
interface does. Later it will be possible to use it without.

Andreas Eversberg 3a8f58ec89 Adding interface support for remote app (chan_lcr). 
chan_lcr can be handled as an interface. This way it is possible to (e.g.):
- make a SIP phone become an LCR extension with all LCR features.
- make conference calls. (untested)
- perform parallel ringing. (ISDN phone and SIP phones can ring in
  parallel.)
- do voice recoding.

It is still also possible to link chan_lcr directly without interface
(as before).

Documentation/howto for that will follow.

Andreas Eversberg a12d7eee22 Splitted GSM support into BS (network) and MS (mobile) part. 2010-05-31 18:45:02 +02:00
Andreas Eversberg b0bd74e35e Replaced polling loop for LCR and chan_lcr with select based event loop. 
Now LCR and chan_lcr will not use any CPU until there is work to do.

Super User ff4d197d5e now LCR features real HDLC bchannel mode. 
-> if initial caller uses pure data mode (or video), the bchannels for this call are handled in HDLC mode. (hardware/software briding is still applicable.)
