I am sending a call from Server A (not asterisk) to an asterisk server and then back out to server A again. Server A generates a CDR for each call and Asterisk also generates a 2 CDR’s (Using Fork option), but I need to able to link all the CDR’s together.
Currently I have managed to extract the ‘Call-ID’ from the sip header generated by Server A and store it in the Asterisk CDR’s which is fine for the inbound flow and asterisk side, but when sending the call back out of Asterisk back to Server A it only stores the ‘Call-ID’ as received from Asterisk.
My thinking is the best option is in asterisk prior to the dial command, to set the ‘Call-ID’ in the Asterisk SIP header to the same id (or an amended version) of the original one stored. As the original Call-ID received is unique then this will be fine, but I cannot find a way of changing it from the default which is automatically generated for the call:
Does anyone know how to change this please? Or have any other suggestions of how I can tie up the CDR’s (bearing in mind the final ‘Server A’ only appears to store the Call-ID (as well as the dialed number etc))
PS. I have been looking at SIPAddHeaders, but obviously this is for adding, not editing/setting headers.
Thank you in advance for any help you can provide!
