Adding SIP header from Manager

I’m having a program that dials out using the asterisk Manager Originate command,
I need the telephone to auto answer the call,
I’m able to make this work on some type of phones with:
'Variable: SIPADDHEADER=Call-Info: Answer-after=0"
and with other phones using this:
"Variable: SIPADDHEADER=Alert-Info: Ring Answer"
I’m trying to find a way to add both of the variables to the header,
I have tryed countless combinations of how to write it but non of them worked, and only 1 header is add.
is it possible to add 2 header variables from manager originate command?

Thank you.
