You can set a limited number of SIP headers independently for applications that initiate an outbound call with one of the following:
A REFER as a result of a blind or consultative transfer
An INVITE as a result of bridged transfer or a CCXML outbound call
Note:
Not all headers that are available to be set on an INVITE are available to be set on a REFER.
You can set the following headers with the VoiceXML <property> element before <transfer> element. In the table, <sip_prop> represents AVAYA_SIPHEADER.session.connection.protocol.sip.
Note:
If you want to set a header in your application, you must use the complete text in your code. For example, code <sip_prop>.callid as AVAYA_SIPHEADER.session.connection.protocol.sip.callid.
