I’m trying to have an automated call to an Aastra SIP phone and have the call auto-answeredby the phone. I know that a SIP call placed to the phone can be auto-answered if a certain SIP header is added to the call. I am able to apply the SIP headers manually and get that working (using SIPAddHeader(Alert-Info: info=alert-autoanswer) in the dialplan, but for call files, I don’t seem to be able to edit any of the sip headers - there is only basic customizations allowed to setup the calls.
Does anyone know how I could place automated outgoing calls that would have the proper sip headers added to it that would allow the call to be auto-answered?
