For the enterprise area it is a device for starters but it is also perfect for home users connected to SIP providers (like for example sipgate or others) operating standard SIP platforms like Asterisk or other standard SIP platforms.

The optiPoint 150 S has been released in 05/2006.

The phone supports a set of basic Call features like Call Transfer, Call Forwarding, Message Waiting Indication and others. The optiPoint 150 S offers among other things an inserted phone directory (100 entries), call list administration and is simple to administer via a Webbrowser.

For larger deployments there is a mechanism available for automatic distribution of configuration files in order to avoid to configure each phone on-site.
