Asterisk variables used/set by chan_capi
|
||||
========================================
|
||||
|
||||
BCHANNELINFO
|
||||
On incomming call, this variable is set with the B-channel information value:
|
||||
'0' : B-channel is used (default)
|
||||
'1' : D-channel is used (not implemented yet)
|
||||
'2' : neither B nor D channel is used (e.g. call waiting)
|
||||
Call-Waiting: an incoming call with BCHANNELINFO not '0' cannot be accepted.
|
||||
Another connection must be dropped before accepting or use
|
||||
capicommand(deflect|<number>) to initiate call deflection to another destination.
|
||||
|
||||
CALLEDTON
|
||||
The 'type of number' value of the called number is saved in this variable on
|
||||
incomming call.
|
||||
|
|
@ -264,6 +272,12 @@ _CALLERHOLDID
|
|||
This variable is inherited as CALLERHOLDID to the dialed channel and will be used
|
||||
if e.g. capicommand(ect) is used to transfer the held call.
|
||||
|
||||
CALLINGSUBADDRESS
|
||||
If set on dial(), the calling subaddress will be set to the content.
|
||||
|
||||
CALLEDSUBADDRESS
|
||||
If set on dial(), the called subaddress will be set to the content.
|
||||
|
||||
CONNECTEDNUMBER
|
||||
Can be set before answering and if set, the content is used for
|
||||
IE 'Connected Number' on answering.

REDIRECTINGNUMBER
|
||||
On incoming call, if the call was redirected to you by someone, the
|
||||
number of the redirecting party is saved in this variable.
|
||||
RDNIS is set as well.
|
||||
|
||||
REDIRECTREASON
|
||||
If the incoming call was redirected to you, this variable is set
|
||||
with the reason value.

CALLINGSUBADDRESS
|

If set on dial(), the calling subaddress will be set to the content.
