[asterisk-users] SIP OPTIONS... Error?

[Alex Vishnev]

no, you need a tag i.e From: <sip:ping at XX.XX.XX.XX>;tag=xxxxxxx, where xxxxxx is a unique identifier

see the definition of SIP Dialog

Dialog: A dialog is a peer-to-peer SIP relationship between two
         UAs that persists for some time.  A dialog is established by
         SIP messages, such as a 2xx response to an INVITE request.  A
         dialog is identified by a call identifier, local tag, and a
         remote tag.  A dialog was formerly known as a call leg in RFC
         2543.
