The VoIP telephony for you and your business.

For all STARFACE users who want to benefit from favourable telephone rates or are looking for an alternative telephone provider, we offer the SIP trunk STARFACE Connect. This allows you to connect your STARFACE VoIP telephone system to the public telephone network via your Internet connection and thus use fully-fledged fixed network telephony.

Preconfigured SIP trunk for PABX

The low-cost IP connection

Preconfigured SIP trunk for your PABX. 

The STARFACE Connect SIP trunk is a system connection which is provided by the SIP network protocol (Session Initiation Protocol). Depending on your requirements, we connect one or more trunks (channels that bundle the data) with your local telephone system to the public telephone network via your Internet connection. This means that you can directly use fully-fledged fixed network telephony.

Activated free of charge with just a few clicks, STARFACE Connect lets you make low-cost calls with high call quality.

The connection to the Internet provides you with further transmission options – now you can also use our STARFACE NEON video meeting function.

Everything from a single source.

With a comprehensive partner network, STARFACE offers the complete supply chain from the DSL connection via the SIP trunk to the telephone system.

Simply use everything from one source.

Inbound and outbound calls are switched via STARFACE Connect and thus via IP. A fixed network connection is therefore no longer required. If you want to continue using your existing phone number range, simply port your phone numbers to STARFACE. You have up to 60 voice channels with high quality at low prices.

Simply save telephone costs.

STARFACE Connect is only used for outgoing calls. Outgoing calls are thus made via the Internet, with the phone number of the fixed network connection being signaled. The called party sees and hears no difference. Your existing fixed network connection remains in place. Incoming calls will be delivered as usual via the previous route.

Simply more phone lines.

Would you like to continue to make calls mainly with your existing provider, but at peak times have too few voice channels to make all the company calls? Then use STARFACE Connect and prevent phone calls from being rejected due to lack of line capacity during peak times.

Telephone calls are possible worldwide to fixed network and mobile phone connections. Service numbers cannot be reached outside Germany.

After activating the STARFACE Services, the video conferencing solution STARFACE NEON is available in your STARFACE system. All users of the STARFACE system are authorised to start video meetings or participate in ongoing meetings.

Active use of the telephony services of STARFACE Connect is not required. In this case, only the charges for the use of STARFACE NEON will appear on your bill.

Yes, that is possible. Many SIP trunk providers can be combined with STARFACE telephone systems. However, STARFACE Connect is already pre-configured and can therefore be activated very easily.

When you register, you will automatically receive a location-independent telephone number with the area code 032. This is used for internal call assignment and is not visible externally. Additional geographical numbers (blocks) are available in many area codes in Germany. 

By default, the previous phone number is displayed unchanged via CLIP no-screening. This means that it is not obvious to others that the call is being made via a different connection than usual. You can freely configure this setting via the STARFACE Admin area. 

Please check the port releases of your firewall. In the Knowledge Base of STARFACE you will find the necessary information.

Both is possible. The booking of new phone numbers can be done directly in the STARFACE Connect customer centre. If numbers are available in the desired area code, activation will take place within a few days. Porting requires at least 15 days and is associated with certain regulatory requirements. The porting request is made via the following form
