Subject: [asterisk-users] SIP Headers
Hi,
I was wondering where I can find a list of SIP Headers which can be used for
the SPA 921 to customise the ringtone and other features for each call.
Here is an example taken from
http://www.voip-info.org/wiki/view/Asterisk+cmd+Page
exten => s,3,SIPAddHeader(answer-after=0)
Many thanks
Dan Journo
