It would be really awesome if we could send a custom SIP header in the INVITE with some custom text to display to the user (for inbound calls).

If we send an INVITE to the phone with X-Awesome-Feature: Hello! it would display the string "Hello!" on the screen, beneath the call info.

This opens the doors to lots of cool functionality, like adding spam ratings to inbound phone calls.
Hi Luke,

We can use Push XML feature to achieve this but need help with push xml server. With SIP NOTIFY feature enabled on the page below. When there is a call comes in, push xml server send a notify with text "hello", phone will display with "hello" when receive it.

For more information about Push XML feature, please refer to doc below:
