# Proxy Extension Status

The Proxy Extension Status page provides connection status of the server registration process. The information on this page is updated according to the refresh rate that is selected at the top of the screen. The default refresh rate is every 30 seconds.

## To view the proxy extension status:

1. From the MiCollab Audio, Web and Video Conferencing main page, click Proxy Extension Status in the navigation pane.

2. Depending on the platform you selected, do one of the following:

For a MiVoice Office 250:

Example results:

The columns display the following information:

- i: The proxy entry number (starts at 0 and increases)

- N: The extension entry number

- U: The username (in most cases this will be the extension number)

- H: The domain

- I: The in-use flag (1 for in use, 0 for not used)

- E: The expire time (when e becomes 0, the server will re-register)

- R: The registration status (when it is 1, the server has properly registered. 0 or -1 indicates the server has not properly registered)

For a Mitel 3300, MiCollab Audio, Web and Video Conferencing registers itself with the Mitel 3300 as a single device based on the settings in Configuring SIP Server. The Proxy Extension Status page displays the results of this registration process. Because this registration process happens often (about every 30 minutes), only the last attempt is displayed. An explanation of the Proxy Extension Status page results follows the example below.
