Use the following syntax:


exten => 100,1,SIPAddHeader(Call-Info:<sip:>\;answer-after=5)

exten => 100,n,Dial(Sip/mynumber)


Note, you can change the ";answer-after=value" option to the desired value in seconds. The example above is set for auto-answer after 5 seconds.


You can enable the option in Zoiper5 under:


1. Open the Zoiper Options window;

2. Automation

3. Enable the "Accept server-side auto answer" option.


Note, this is supported only for SIP.
