1 Pre-requisites and Architectures

1.1 Pre-requisites

VoIP characteristics

Major VoIP characteristics for Softphone applications are indicated in document [3]

" Reader of this document must be familiar with VoIP concepts and IP Softphone

applications.

In this document, we consider that:

• OmniPCX IP addressing has already been completed.

• Racks and boards are created and in service.

• VoIP boards (GD or INTIP) are configured and in service.

• Corresponding software locks are available on OmniPCX side.

• Ghost Z sets (for the Nomadic VoIP mode) are defined on OmniPCX side.

• H323 trunk groups (used for the Nomadic VoIP mode) have been created.

• The Nomadic gateway has been configured through the Web Administration tool

(this gateway is in fact the IP address of the INTIP/GD board).

Main restrictions and limitations

• IP Softphone (thick or Web client), as well as 4980 Softphone in Nomadic VoIP mode, is not

supported in the Microsoft Terminal Server and Citrix® environments.

• Voice mails 4635 and 4645 cannot be addressed by the IP Web Softphone application (no

direct link to the voice mails). Note that voice mails 4635 and 4645 can be addressed by the

4980 Softphone (IP or Nomadic VoIP mode) through the voice mail service dialog box as
