SIP endpoints, such as SIP telephones, cell phones, PDAs, or workstations, use user agent (UA) applications to provide the interface between the users and the SIP network.
SIP endpoint support is fully integrated into IP Office. No other components are needed. SIP endpoints require VCM module capacity like any other IP phone.
SIP extensions function like any other
IP Office extension.
IP Office provides the following functionality:
Make and receive calls to any other extension, independent of type of extension.
Deliver end-to-end media. During calls between two SIP extensions or a SIP extension and an Avaya IP telephone, IP Office transmits audio end-to-end for basic telephone calls. Conferencing requires a VCM resource.
Use short codes and authorization codes.
Transmit in band call progress tones.
Register endpoint using authentication with username and password.
Support Auto-create. Successful endpoint registration uses a third-party license.
Several extensions can register on one IP address, each using a license. This enables the connection of SIP terminal adapters with more than one analog port, giving a different extension number to each port.
