P‐Intrinsics SIP Header: If your call‐associated information does not fit in the SIP UUI header information, you can use P‐Intrinsics header information to pass the information between SIP‐enabled applications. P‐Intrinsicsinformation is contained in an Avaya custom SIP Private Header (P‐Header).
For further information on how to use/create this SIP-Header, please check the example applications on DevConnect. E.g. Front-end Avaya Aura® Experience Portal and SIP-enabled Avaya Aura® Contact Center
