cisco 7965 SIP HEADER AUTO ANSWER

[jleipert79]

Is there a way to add a sip header to allow the phone to auto answer 

I already tried the lines below

Thanks

exten => 1000,n,SipAddHeader(uri=answer-after=0)
exten => 1000,n,SIPAddHeader(Alert-Info:info=alert-autoanswer)
exten => 1000,n,SIPAddHeader(Alert-Info: Ring Answer)
exten => 1000,n,SIPAddHeader(Call-Info: answer-after=0)
exten => 1000,n,SIPAddHeader(Call-Info:\;answer-after=0)

If you use CUCM, where the phone registers to, there is a setting for auto answer under the directory number

Hey thanks for responding! unfortunately I'm not using CUCM. I'm using Asterisk/Freepbx. I can get it to Auto Answer by extention. But I would like to  Auto Answer by SIP Header. Thanks again

Stupid question:
Which difference are you trying to achieve? What is your intention?

I'm trying to create a page group. Without creating another extension on
the phones with auto answer enabled.

see below (this works on SPA504G cisco)

exten => 2990,1,Answer
;exten => 2990,n,Macro(user-callerid,)
exten => 2990,n,SIPAddHeader(Call-Info: answer-after=0)
exten => 2990,n,SIPAddHeader(Call-Info:\;answer-after=0)
exten => 2990,n,Set(SIP_CODEC=ulaw)
exten =>
2990,n,Page(SIP/2091&SIP/2053&SIP/2052&SIP/2051&SIP/2050&SIP/2049&SIP/2048&SIP/2047&SIP/2046&SIP/2045&SIP/2044&SIP/2043&SIP/2042&SIP/2041&SIP/2040&SIP/2144&SIP/2145&SIP/2003&SIP/2004&SIP/2005&SIP/2006&SIP/2007&SIP/2008&SIP/2109&SIP/2010&SIP/2011&SIP/2012&SIP/2101&SIP/2102&SIP/2103&SIP/2104&SIP/2105&SIP/2106&SIP/2107&SIP/2108&SIP/2110&SIP/2111&SIP/2112&SIP/2113&SIP/2114&SIP/2115&SIP/2116&SIP/2117&SIP/2118&SIP/2119&SIP/2120&SIP/2121&SIP/2121&SIP/2122&SIP/2123&SIP/2124&SIP/2125&SIP/2126&SIP/2127&SIP/2128&SIP/2129&SIP/2130&SIP/2131&SIP/2132&SIP/2133&SIP/2134&SIP/2136&SIP/2137&SIP/2138&SIP/2139&SIP/2140&SIP/2141&SIP/2142&SIP/2143&SIP/2201&SIP/2202&SIP/2800&SIP/2802&SIP/2803&SIP/2805&SIP/2135)
