IP Telephony (IPT) update NCAB Presentation 18-Jun-2003 Jeff Custard Teresa Shibao

Outline for today’s presentation Current state of deployment Overview of changes and enhancements Schedule for remaining deployment Input on dates and contacts Future items Potential services and enhancements

VoIP – a typical migration Step 1   Pilot stage—the IP network is introduced, and a very limited number of users are given IP service. In this initial deployment, which often will include the telecom or IT group, users sometimes retain their conventional phones side-by-side with IP phones. Usually, however, they move immediately onto the new system. When the pilot trial is stable and satisfactory for a number of weeks, it can be expanded. Step 2   User block migration—a block of users is moved (usually over a weekend) from the conventional voice network to the IP network. The block can be chosen as a geographical group, a group sharing a block of directory numbers (DNs), or a community of interest, such as the purchasing department. Step 3   Further user block migration—the number of users moved in a block is determined by the maximum number of users the telecom staff can move over a weekend, and the number of weekends the telecom department is prepared to work. In general, migration should be completed as quickly as possible. Taken from: http://www.cisco.com/univercd/cc/td/doc/product/voice/ip_tele/network/dgmigrt.htm

Current state of deployment 3 Cisco Call Managers (CCMs) 1 Unity voicemail server Misc. IPT servers (e.g., for services, billing, etc.) ~620 IP phones deployed ~500 users

New IPT application servers Cisco Emergency Responder (CER) - provides location of IP phones and notifies security about 911 calls Cisco Integrated Contact Distribution (ICD) - a “help desk” solution

Schedule for remaining IPT deployment Draft schedule for converting the rest of the organization from the PBX based system to the IPT based system now available Goal is to complete this by the end of the 2003 calendar year. You may view this schedule at: https://www.scd.ucar.edu/nets/projects/voip/documentation/internal/ncar-ipt-deployment-schedule.html Input on Technical contact(s) Administrative contact(s) Please review this schedule. We are asking for your input on the following items: Dates for the various groups: if you know of major conflicts, meetings, or key personnel may may be absent, etc., during the times we've allotted, please let us know so we can make adjustments now if necessary. Technical and Administrative contact information: I think we have most of these already (even though you don't see them all on the schedule yet), but we would like your input to assure we don't miss somebody you would like kept in the loop on everything. We are planning on working closely with these individuals regarding the specific changes and then counting on them to notify their respective user groups.

End state of deployment 4 Cisco Call Managers (CCMs) 1 Cisco Unity voicemail server Misc. IPT servers (e.g., for services, billing, etc.) ~1,800 IP phones deployed ~1,500 users on new IPT systems

IPT is a driver for increased redundancy and network resiliency IPT is a driver for increased redundancy and network resiliency. These improvements do not have to cost a ton of money, but we do need to make significant changes in our overall network design to achieve them (such as going to a layer3 backbone).

Futures? “SoftPhone” support? Additional “services” and directory functions from phones? Intra-FRGP member IPT? Intra-I2 member IPT?
