[asterisk-dev] adding SIP Headers a SIP dialog

[Marco Happenhofer]

Hi,

I need to insert a SIP Header in all SIP Messages for a single dialog.
I tried the SIPAddHeader Method, but with this function the header is 
only added to the first SIP INVITE.

Is there any possibility to add SIP Headers for the dialog (including 
ACK and BYE), not only for the single Message?

If no, how much effort has to be taken to implement this feature?

Thanks, marco
