First, thank you for building a soft phone that shows the SIP packets. I have been using SIPp for debugging up until now, but phonerlite is much easier to work with.
One feature that we use on our network phone system is X-Headers. I have looked through the application and do not see a way to specify the X-Header that go with the INVITE request. Is there an hidden feature that I could use to add additional header fields?
Thank you
