[SIPForum-techwg] Call Origin

[Melissa Melnik]

Looking for a SIP header that contains a field to indicate call origin.
The Media Gateway is responsible for resolving call origin. It
determines if the call came from PBX (internal/private) or PSTN
(external/public). A requirement of the Gateway is to send this
information in the SIP Call Request to a VoIP user. Please let me know
if there is a standard header for call origin.

 

Thank you!
