According to section 8.1.1.3 of RFC 3261, the From
header MUST have a tag
parameter. This is one of the pieces of data used to identify the dialog. (The others are Call-ID
and the tag
on the To
header, generated by the UAS.) One the examples shown in the RFC is:
From: sip:+12125551212@phone2net.com;tag=887s
When looking at the SIP message received by the Mobicents container, is there a tag
parameter on the From
header?
