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.
causing GCC to emit a warning about incompatible pointer types when
initializing lcr_tech. Fix this by adding necessary const's to lcr_request.

gcc thinks that the implicit declaration in module.h is different from
the one in channel.h, and issues a warning about incompatible pointer
types. A forward declaration before including module.h fixes this.
Due to some brain-deadness in Ast, including channel.h before module.h
causes the compilation fail altogether.

union member ast_frame_subclass::codec (instead of ast_frame_subclass::integer).
The old code caused an error in some environments, eg big endian Arm (armeb):
"__ast_read: Dropping incompatible voice frame on lcr/1 of format alaw ..."

Hi,
I tried to tackle the issue that 'core stop|restart when convenient' won't
work because unloading chan_lcr does not work.
The issue is that the thread blocks in select().
I tried to move the clean-up work from after the main select loop to the
module unloading code, make that loop a real infinite loop and replaced
pthread_join() by pthred_cancel().
The result seems to work.
Proposed patch attached.
Unloading chan_lcr while it has open channels is fatal, with or without
that patch.
Greetings,

There are two modes:
The remote mode is used to route a call directly to Asterisk or route a
call from Asterisk to an ISDN interface. (the old way)
The interface mode is used to handle chan_lcr as an interface, so calls
from Asterisk can be routed and behave like they come from an ISDN
interface. (documentation for that will follow)
configure script will automatically detect new asterisk API, so there is
no need for different chan_lcr.c source codes.
'type', 'presentation', and 'screening indicator' are now transcoded.
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.
The problem: for some reason, asterisk silently switches write_format
from SLINEAR to ALAW when using app_rxfax, thereby effectively disabling
automatic conversion SLINEAR->ALAW and thereby breaking app_rxfax after
the first call to ast_write(). Read: instantly, after the first data frame.
Older versions of LCR work flawlessly, until we find out, what really triggers
the problem, we at least switch the channel back, since it never makes
sense to send something different than ALAW to chan_lcr.
Tests with asterisk 1.6.2.13 showed that callerid did not work
unless the ast->cid structure is set to zero.
Thanx for Marcello for prividing this fix.
I changed it a bit, so the redirection number is converted from
national/international format into numerical format. (adding prefixes)
If there is still a problem with it, let me know.
