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.
