OpenStage IP (SIP) phone family
SIP and HFA phone variants
Each model of OpenStage IP phones is available as a phone variant with the open standards for SIP voice communication or with the proprietary protocol of Siemens Enterprise Communications (CorNet-IP, also known as HFA = HiPath Feature Access). In addition to the standard-based SIP (RFC 3261) VoIP protocol, OpenStage SIP phones support even more features such as consultation, local 3-way conference, multilines and team features that allow a high degree of flexibility in your IT strategy.
OpenStage telephones are easy to deploy and ongoing administration is simple. The telephones can be centrally managed as part of an IT environment. Each OpenStage IP phone provides an integrated Ethernet switch (exception: OpenStage 5 SIP). The network is accessed by 10/100 Base-T or as a variant via Gigabit Ethernet (exceptions: OpenStage 5 SIP, OpenStage 15, and OpenStage 20 E). All phones support 802.3af Power over LAN.
OpenStage SIP phones are supported by OpenScape Voice and Asterisk.
Please note: optiPoint/OpenStage/OpenScape. HFA and SIP versions are identical. Only the installed Software is different. You can order your phones with your suitable software.
