asterisk users - Mar 2018 - Setting outgoing CALLERID without changing CDR(src)

??? I thought I had found and answer to this question by using 
CALLERID(ani) but it seems that only works on versions prior to 12.? On 
Asterisk 13 setting CALLERID(num) before dialing to an external trunk 
always changes CDR(src) to the number you set and the original extension 
number that dialed is lost.? How are you handling this?? Am I forced to 
use a custom field to keep the original caller number?? My billing 
software uses the src field to get the extension that dialed the call.? 
Any tips?

What does your external trunk use as sources for callerID? For example
if your provider supports PAI and sets this headers as callerID, your
problem is solved. Otherwise you could for example use the custom csv
output and set a custom CDR field (that stores the original src) in the
place of src.
