Installing and Configuring Mitel IP Phones
Introduction
The Desktop IP Line from Mitel provides a wide range of Session Initiation Protocol (SIP) telephones for
IP communication. The phones and devices feature a context-sensitive softkey display combination –
technology that was pioneered by Mitel more than two decades ago. This combination reduces user
uncertainty while supporting efficient call processing, application access, and preferences programming
because it displays only those prompts appropriate to the function in progress. Mitel phones are fully
interoperable and configurable with the NetVanta Enterprise Communications Server. The purpose of this
technical note is to provide instructions for installing and configuring Mitel phones with the UC server.
Known Integration Issues
Known integration issues include:
Redirection to voicemail may fail on the Mitel 5235 series if do-not-disturb (DND) is enabled.
