Hello, maybe the second parameter (‘contact’) of the ‘is_contact_registered’ function [1] could be useful? And speaking about Expires: 0 — according to SIP RFC [2] it’s absolutely normal, it means tat a device disables its registration, this is done either by sending Expires: 0 SIP header, or by adding ;expires=0 as a parameter to the Contact header.
