H.323 Gatekeeper Peering

  • The Global Dialing Scheme

(GDS) provides a structure for peering between gatekeepers, such that any endpoint associated with a zone may dial an endpoint in any other zone.

ENUM is Convergence

ENUM at its most basic is the convergence of the Public Switched Telephone Network (PSTN) and Internet Protocol (IP) networks; it is the mapping of a telephone number from the PSTN to Internet functionalities. ENUM takes a complete, international telephone number and resolves it to a fully qualified domain name address using a Domain Name Service (DNS)-based architecture.

User A

Invite: 19135551212 From: 12025551212 Invite: SIP: UserB@illuminet.com From: 12025551212 In this example, User A attempts to contact User B who is on a VoIP network and uses a SIP phone. 1. User A dials the global E.164 number for User B. 2. The SSP sends an IAM message via SS7 to a SG (which is part of the Media Gateway Controller / Media Gateway). 3. The Media Gateway Controller sends an invite message to the nearest Proxy Server. 4. Proxy Server A does not know User B address; therefore it contacts an ENUM Server. 5. The ENUM Server returns the address of User B. 6. Proxy A sends invite message to User B’s Proxy Server B 7. Proxy Server B passes the invite to User B 8. If User B accepts the call, there is a two-way RTP path established between User B and the Media Gateway controller. A two-way path is also established between the Media Gateway and User A. At this point User A is able to communicate with User B.

What are the major benefits?

  • Linking to together VoIP islands on the Internet, enabling all

Internet services – VoIP PBX and also “Carrier” networks

  • Allowing terminals on the Internet to be reached from the PSTN

– Terminals on the PSTN may dial only numbers and not URIs

  • ENUM can be used for any URI = any service

– mailto, fax, video, … – sms, mms, … – h323, pres, im, … – http, ft, – certificates, locations, …

Enum

ENUM was developed as a solution to the question of how network elements can find services on the Internet using

  • nly a telephone number, and how telephones, which

have an input mechanism limited to twelve keys on a keypad, can be used to access Internet services. ENUM at its most basic is the convergence of PSTN and IP networks; it is the mapping of a telephone number from the public switched telephone network to Internet functionalities.

Thursday, February 11, 2010

slide-37
SLIDE 37

Will ENUM telephone routing confuse the PSTN routing system?

  • It is a core principle that in providing a unified resource directory

service, ENUM will not change the existing right-to-use rules and principles for telephone numbers.

  • ENUM is not intended to change how telephone numbers are

administered, but instead facilitate a wide range of applications using phone numbers as subscriber names.

  • ENUM also will not interfere with existing PSTN functions and

technology, such as circuit switching, SS7 (ISUP or TCAP), or Intelligent Networking, where similar resource discovery activities are performed through the PSTN legacy technologies. ENUM Subscriber edits NAPTR
