Voice over IP (VoIP) SIP Telephony characters after "@" is the "Domain Name" or the "SIP Domain". The IP address of the OpenCom 100 must always be used here. ■ A STUN server (Simple Traversal of UDP over NAT) or a SIP proxy is not required because internal SIP subscribers on the LAN are directly connected to the OpenCom 100. Switch these functions off if possible. ■ With a SIP terminal, you can enter an international phone number with a leading plus. When you enter a call number in the E.123 format, the plus char is substituted by the "00" number sequence and the immediate line seizure via the standard route is activated for the call. If you prefer to dial in this number format, you should activate the international call number conversion (see E.164 conversion starting on page 163). Features SIP subscribers can establish connections to all other terminals and trunks. The SIP protocol generally works with block dialling. This is why the selected call number is only activated after an internal clock has expired or activated immediately via the hash key ("#") when dialling. This is why code number procedures without the hash key and code number procedures with a concluding hash key can be used. An overview of code number procedures that can be used is located in the Configurator on the System Info: Codes page. Activate "SIP phones". Please also note the corresponding information in the "OpenCom 100, Operation on Standard Terminals" user guide. Alongside code number procedures, SIP subscribers can also use a series of functional features realized via the SIP protocol. The OpenCom 100 is the ending for all SIP connections as opposed to what is usually the case on the Internet. This enables SIP subscribers to use OpenCom 100 features. Direct data exchange is thus not possible between two SIP subscribers. The following table shows the possible features. Features Incoming and outgoing calls with call number display (CLIP) Parallel connection of multiple SIP subscribers Enquiry, toggling, call waiting, threeway conference, reject Notes A SIP telephone requires a call number display for CLIP. SIP subscribers must be logged on under the same user identification. Operation or feature must be available on the SIP telephone or in the SIP software. 119
