Hello All, I've asked this on the asterisk-dev list, so sorry for cross-posting. So far I'm not sure how to accomplish this without looking at the source code or looking at some other way to get around this issue. 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? I've also posted this question to the forums here: http://forums.asterisk.org/viewtopic.php?f=1&t=89190 Many thanks, Steve -------------------- http://www.stevemccann.net

This isn't a development question, as it doesn't relate to the actual
Asterisk source code itself. Cross-posting across the -dev and -users
lists isn't helpful either, as pretty much everyone who is subscribed
to the asterisk-dev list is also subscribed to the asterisk-users
list.

As SIPAddHeader is a dialplan application and not a dialplan function,
it cannot be used from a call file. One approach to performing an
outbound call that requires SIPAddHeader - and that doesn't rely on
undocumented behaviour - is to use the call file to create a Local
channel in the dialplan that dials the SIP channel, and use
SIPAddHeader from there. A quick Google indicates others have used a
similar approach in the past as well [1].

So I take it in the call file you have it set to call Dial(SIP/something) ?
If rather than dialling the sip destination immediately you dialled a
local channel then it could add the custom header and then initiate the
dial to the sip destination.

Hello Steve,

Have you tried to send the automated call to your dialplan instead of the phone?

For example, instead of calling SIP/aastra_phone call Local/aastra_phone@auto-answer-context and tweak auto-answer-context from your dialplan as needed.

HTH,
Ioan
