asterisk users - Jun 2015 - Can dial plan handle new proprietary SIP HEADER fields? How?

Dear asterisk-users,

I have listened that a diaplan on Asterisk can extract information from
proprietary SIP messages header fields. That is, if Asterisk receives a SIP
message with a modified HEADER (containing proprietary fields) , is it possible
to program the dial plan to make Asterisk extract the values of such fields,
being possible to handle such values in diaplan, isn't it?

If it is true, is it also possible to use dial plan to make Asterisk include
proprietary SIP HEADER fields in a specific SIP message?

Any hint will be very helpful!


Best regards.
