VoIP telephony for you and your business.

All users wishing to benefit from low rates, as well as others looking to switch providers, can take advantage of the STARFACE Connect SIP trunk. You can use it to link your VoIP telephone system to the public phone network via your Internet connection and enjoy full landline service.

Preconfigured SIP trunk for PABX

A cost-effective IP connection

A preconfigured SIP trunk for your telecommunications system.

The STARFACE Connect SIP trunk uses the Session Initiation Protocol (SIP). Depending on your needs, we connect one or more trunks (channels that bundle data) and your local system to the public telephone network via your Internet link. This lets you directly take advantage of landline phone services.

After enabling it free of charge with just a few clicks, you can start using Connect to inexpensively make calls with high voice quality. And thanks to the Internet connection, you also benefit from other options – like our STARFACE NEON videoconferencing function.

Why choose STARFACE Connect?

It’s professional and secure.

All of the servers are located in Germany, where they are required to comply with the strict German data privacy guidelines. Hosting at German data centers also gives you greater legal security: contracts, our headquarters, and the responsible courts for resolving any conflicts are all subject to German laws.

Get everything from one source for maximum convenience.

Incoming and outgoing calls are routed via STARFACE Connect and therefore by IP. This means that you no longer need a fixed landline connection. If you would like to continue using the same numbers as in the past, simply port them to STARFACE. You can take advantage of up to 99 high-quality voice channels at low rates.

Simply save telephone costs.

Connect only comes into play for outgoing calls. Although they are routed via the Internet, the number of your landline connection appears in the other party’s display. They can’t see or hear any difference whatsoever. Incoming calls arrive through the same channels as in the past.

The more phone lines, the merrier.

Would you like to mostly continue relying on your current provider, but at peak times don’t have enough voice channels to handle all of your company’s calls? If that’s the case, STARFACE Connect is the solution! It prevents calls from being rejected due to insufficient line capacities.

It isn’t necessary to actively use the telephony services of Connect. If you don’t, only the fees for using STARFACE NEON will appear on your invoice.

Yes, that is possible. Many other SIP trunk providers can be combined with STARFACE equipment. However, STARFACE Connect is preconfigured, making it very easy to enable and use at any tie.

When registering, you automatically receive a call number with the prefix 032 that isn’t associated with any particular location. It is only used for internally allocating calls and not visible to others. Additional geographically assigned call numbers and number blocks are also available for many German prefixes.

The standard procedure is for your existing call number to continue to be displayed while applying the “clip no screening” procedure. This means that others can’t tell that you are actually calling from a different number than usual. You can freely configure this setting in the administration section.

If this happens, please check which ports are enabled in your firewall settings. You can find the required settings in the STARFACE knowledge base.

Yes, you can do both of things things. You can book new call numbers in the customer center for STARFACE Connect. If numbers are available for the desired prefix range, they will be activated within a few days. Porting takes at least 15 days and involves meeting certain regulatory requirements. Use the following form to request the porting of numbers.
