Hi,
Even variable is not exist you can parse sip-headers and extract variables via regex:
bellow example for parse to-header
<action application="set" data="act_nmbr=${regex(${sip_h_To}|^\<sip:(\d*)\@.*\>.*$|0%1)}"/>

Hey,

 

I’ve currently got a dial plan set up to receive faxes which looks like:
                        <action application="rxfax" data="/var/spool/fax/FAX-${destination_number}-${caller_id_number}-${uuid}.tif"/>

 

I’m just wondering what $destination_number variable is set to. In our SIP Header we’re sending a different ‘SIP Display info’ to what this variable is set to and I can’t seem to find what that variable is actually looking at.

 

Thanks,

Kyle
