Dear All,

I know SIP is taboo, in some groups, but we need to confront the possibilities.

For information:

SIP or not to SIP. Since SIP runs on a IP Network, I think we need to consider how to interwork supplementary services between H.323, SIP and WAP/WTA. As part of the TIPHON's Forward looking IP network configurations. Could SIP and WAP/WTA be looked at as (BES) or will it be part of the TIPHON's family of applications.

If we took the concept of the SCN where for example:

SCN world | IP world --------------------------------- Q.931 call control can = H.323/h.225 Q.932 NCAS/CAS can = (SIP)into H.323/h.450x/h.246 Annex?

Same thing applies to SS7 where:

SCN | IP world ---------------------------------- ISUP can = H.323/h.246 Annex? TCAP(services) can = (SIP)into H.323/h.450x/h.246 Annex?

The services and requirements we are looking to provide in TIPHON. I believe we will need to support both SIP and H.323. Not only in the Gateway decomposition but within the core TIPHON applications.

Regards,

Ed

SIP is Happening

A week before Spring '99 VON, the first SIP Bakeoff took place at Columbia University. Eighteen engineering groups representing fourteen vendors and research organizations met to jointly test the operation of their Internet Telephony SIP products.

At the end of the event, nearly all of the implementations had achieved interoperability for call setup and media capability negotiation for multimedia calls. Several were interoperable on the first try, and most others after minor changes were made. Systems being tested included user agents and servers running on a various of operating systems. The event was able to show subscribers can move from location to location, (anywhere on the Internet), with phone calls following them automatically, regardless of the provider of the hardware or software. Users could also forward calls to any Internet destination or telephone number. Some groups also tested advanced features such as call screening and user authentication.

Organizations participating in the SIP interoperability testing came from the US, Canada, Sweden, Finland and the UK and included, among others: 3Com, Alcatel, Cisco, British Telecom, Columbia University, Dialogic, dynamicsoft, Ellemtel, Ericsson, Helsinki University of Technology, Hewlett-Packard, Lucent, Mediatrix, Nortel, and Pingtel.

During 1998 the IP Telephony MoU was successful in creating and contributing a suggested Call Detail Record (CDR) for the VON Industry. In 1999 our focus has shifted to contributing a SNMP-2 MIB for the Industry which reflects the needs of Service Providers.

As a follow up to a discussion held at the IP Telephony Retreat in February and a follow up meeting which was held during Spring '99 VON, the next MoU-MIB meeting is scheduled to take place May 19-20 at the JFK Airport Hilton. At this meeting we will be discussing the creation of an IP Telephony MIB which is designed based on the needs of Service Providers.

Hans Eriksson of Telia writes: "During the spring Telia has together with Clarent, Inter-tel and Nokia gathered a common basic MIB for gateways. As we are going for a multi-vendor deployment a common MIB is absolutely crucial for us. The current proposal is a collection of stuff from existing MIBs (H.341, E1, ISDN, MIB-II, etc) as well as some additions. This is a very basic first cut that needs to be extended in the near future. Telia welcomes this initiative to form a MoU-MIB group and will bring our work and resources to progress this."

Hans Eriksson from Telia will be at the JFK Meeting and will help lead the discussions together with Carl Ford and Jeff Pulver. If you are a service provider or equipment vendor, and if would you would like to attend this meeting, please email: mib@pulver.com or visit: ( http://pulver.com/mou ) for more information.
