Fax issue
« on: April 25, 2013, 12:58:32 PM »
Hi, i am tryind to receive a fax with yate.
I use a script from https://github.com/shimaore/yate/blob/master/share/scripts/detector.php
I am iniciating a fax with pbxassist.
For example, in my regexroute are route
^964$=external/nodata/fax.php;called=${caller};
I use fax.php to iniciate fax receiving and detector.php
to write it into a file. The problem is, that in detector.php
filename consist of billid, called and called, but when it writes
a file it writes in form billid caller caller

For example, i make a call from extension 022768482 to 022244340
I make one change in detector.php i v added a print of $num varueble.

My pbxassist transfer trigger:
[transfer]
; blind transfer: make call on behalf of peer, hangup this
; key: *1nnnnn*
trigger=\*1\([0-9]\+\)\#$
target=\1
;trigger=*3\([0-9]\+\)\*$
;target=\1
First time script detects correctly, but after it detect both as caller.
I tryed regexroute with ^964$=external/nodata/fax.php
but it returns, that there is no called after making a transfer

<ExtModReceiver:WARN> Error: 'NUM 1366916013-1_022768482-022244340'
