[SR-Users] presence_dialoginfo- first NOTIFY - force_dummy_dialog

[Daniel-Constantin Mierla]

Hi Luis,

for my own clarification, the call-id attribute is not in the static body:

#define DIALOGINFO_EMPTY_BODY "<dialog-info>\
<dialog id=\"615293b33c62dec073e05d9421e9f48b\" direction=\"recipient\">\
<state>terminated</state>\
</dialog>\
</dialog-info>"

I couldn't spot where it would be added later... is id attribute enough,
or I missed the point where call-id is set?

Cheers,
Daniel
