I have done this for internal call with

;;;grandstream;;;
exten => _12X,1,Set(_ALERT_INFO=<http://127.0.0.1>\;info=internal)
exten => _12X,2,Dial(SIP/${EXTEN},30,tTr)

;;;linksys;;;
exten => _1XX,1,SetVar(_ALERT_INFO=Simple-1)
exten => _1XX,2,Dial(SIP/${EXTEN},30,Tr)



;;;polycom;;;
exten => s,n,Set(_ALERT_INFO=Custom 1)

or when it doesnt works best solution is

exten => s,n,,SIPAddHeader(Alert-Info: Custom 1)
