If progress message is received, go into proceeding state.
Send audio, if proceeding/alerting state, so RTP stream is sent in both
directions. This is essential when using NAT.
In order to provide internal tones, a clock is used to generate
chunks of 160 samples. If no tones are provided and if audio is
bridged, it is forwarded as usual.
In order to provide early audio on SIP trunk, "tones yes" must be set
at interface.conf.
In order to receive early audio from SIP trunk, "earlyb yes" must be
set at interface.conf.
This is required, so inactive parties will be marked as beeing "on hold".
These parties will be removed from the bridge, so the partyline is not
disturbed by hold music comming from inactive parties.
Thanx to Atul for pointing to this bug.
Usage: Dial(LCR/<interface>/<digits>/<options>)
The interface must match the interface name in interface.conf. If omitted,
the first remote interface is used.
Example:
Dial(LCR/ast/123) will send a call to LCR and select remote interface
'ast'.
Dial(LCR//123) will send a call to LCR and select the first remote
interface.
Now it is possible to have multiple remote interfaces.
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.
For external calls, the list of interfaces is used to select the first
available/not busy interface. If the interface list is stated with +,
the call is forked to all interfaces.
otherwise. Note: Autoconf manual says that using $< in ordinary make
rules is not portable, but LCR is Linux specific anyway.

hardcoded location. This is practically the same as the reverted part of
commit 51655a18 except that $(DESTDIR) *is not* prepended to CC defines;
doing so would break staged installs.

if LCR is not being run as root. The lock directory, on the contrary,
must be writable by the lcr process, and can be configured by the user.
