SIEMENS phones
Three series of SIP phones are available - Gigaset, optiPoint, and (new) OpenStage. See the corresponding sections for more information.
Gigaset Series
The Gigaset series of phones is based on series of DECT phones using the same name. The handsets are identical to the ones for use in a PSTN or ISDN environment, the base stations have been enhanced to provide the additional functionality. They seem to share a common platform named 'Chagall'. The Gigaset IP phone series is targeted towards home installations. However, the handsets can be used in larger, HiCom based enviroments as well. There are three categories of handsets, C-series (value), S-series (full featured), and SL-series (full featured and smaller sized).
Gigaset C450IP / C460IP
The Gigaset C450IP is a DECT dual mode SIP/PSTN phone. It has been designed for the consumer market but it easy integration in Asterisk makes it very applicable to professional installations. As it contains LGPL'd software (libOSIP) one can rebuild the firmware with a new libOSIP.
Gigaset C470IP / C475IP
The Gigaset C470IP supersedes the C450IP, featuring an improved handset. The C475IP also features an integrated answering machine, and supports 6 SIP account registrations
Gigaset S450IP
The Gigaset S450IP is similar to the C450IP, but uses a different handset and an almost identical yet more powerful (RAM/ROM size, CPU speed) hardware base.
Gigaset S675IP & S685IP
The Gigaset S675IP and S685IP seem to be a successors to the S450IP, it uses an improved handset and adds an integrated answering machine. The 675 was never officially imported into the UK, instead the 685 is the same except for adding Bluetooth to the handset for hands-free and receiving contacts in vCard format. Compared to the S450IP they use an improved handset and add an integrated answering machine.
Gigaset SL75 WLAN WLAN/SIP
The Siemens Gigaset SL75 WLAN is not based on the DECT series. It is a Wifi telephone with a camera. You can also read e-mails with it or use it as an IMS. The device seems to be running linux so it is probable that it will do much more than that.
OptiPoint Series
According to the datasheet and user manuals the phones support standard SIP as well as features of the HiPath8000 system, but also BroadSoft and Sylantro can be selected ("server type"). For all systems various business features are supported (keyset, call park, pickup, 3PCC...). The phones do not support STUN, but features like DNS SRV and survivability, QoS and extensive trace capabilities.
Actual application SW version is V7.0, unfortunately there is no SW in the public download area...
A WiFi with SIP protocol is also available: optiPoint WL 2 professional S.
Provisioning and maintenance can be done by either the (free-of-charge) tool "Deployment Service" (this can be downloaded from their web site www.siemens.com/hipath) or by (XML) configuration files or via local menue / web admin pages.
