What do you mean by "package"?  You can use esl and events to send custom info.

Hi,

I would like to add a custom SIP INFO package, controlled by an event socket application.

I know I can use sip_h variables to set header fields, but is there a better way to identify to sofia
that I am adding a custom SIP INFO package?

Also, do you have any tips on processing INFO events and sending INFO messages?

Thanks!
David
