-----Original Message----- From: Lyons, Terry Sent: Monday, March 18, 2002 4:47 PM To: imtch323implementors@mail.imtc.org Cc: ITU-SG16@echo.jf.INTEL.COM; Lyons, Terry Subject: Question about "packet-based network originated call"
Is this restriction of H.225.0 enforceable?
Numbering plan identification (octet No. 3, bits 1-4)
Encoded following the values and rules of Table 4-11/Q.931. Anumber in the form of a dialed digit string should be coded as '0000' Unknown. If set to '1001' (Private Numbering Plan) in a packet-based network originated call, this indicates that: 1) the dialed digit string is not present in Setup; and 2) the call will be routed via an alias address in the User-user information.
- How can one tell if it's a "packet-based network originated call"?
All H.323 Setups of practical interest are carried over a packet-based network, ie. IP, but did they originate there or were they gatewayed from a circuit-based network? Or is the quoted phrase trying to make some other distinction?
- Talk of the dialed digit string and routing seems to fit best 7.2.2.4
Called Party Number. However, the passage reproduced above comes from 7.2.2.6 Calling Party Number.
