Detailed Description

DAHDI for Pseudo TDM.

Author:: Mark Spencer <markster@digium.com>

Connects to the DAHDI telephony library as well as libpri. Libpri is optional and needed only if you are going to use ISDN connections.

You need to install libraries before you attempt to compile and install the DAHDI channel.

Typically, how many rings before we should send Caller*ID.

Note:: Define ZHONE_HACK to cause us to go off hook and then back on hook when the user hangs up to reset the state machine so ring works properly. This is used to be able to support kewlstart by putting the zhone in groundstart mode since their forward disconnect supervision is entirely broken even though their documentation says it isn't and their support is entirely unwilling to provide any assistance with their channel banks even though their web site says they support their products for life.

static int dahdi_cc_callback	(	struct ast_channel *	inbound,
		const char *	dest,
		ast_cc_callback_fn	callback
	)		`[static]`

Callback made when dial failed to get a channel out of dahdi_request().

Since:: 1.8

Parameters:

inbound	Incoming asterisk channel.
dest	Same dial string passed to dahdi_request().
callback	Callback into CC core to announce a busy channel available for CC.

This callback acts like a forked dial with all prongs of the fork busy. Essentially, for each channel that could have taken the call, indicate that it is busy.

Return values:

0	on success.
-1	on error.

Parameters:

dahdichan	"Physical" DAHDI channel (e.g: DAHDI/5)
flag	on 1 to enable, 0 to disable, -1 return dnd value

chan_dahdi has a DND (Do Not Disturb) mode for each dahdichan (physical DAHDI channel). Use this to enable or disable it.

Bug:: the use of the word "channel" for those dahdichans is really confusing.

static void notify_message	(	char *	mailbox_full,

Send MWI state change.

mailbox_full This is the mailbox associated with the FXO line that the MWI state has changed on.
thereornot This argument should simply be set to 1 or 0, to indicate whether there are messages waiting or not.

Returns:: nothing

This function does two things:

1) It generates an internal Asterisk event notifying any other module that cares about MWI that the state of a mailbox has changed.

2) It runs the script specified by the mwimonitornotify option to allow some custom handling of the state change.
