Enterprise SIP for your private branch exchange (PBX)

Inbound calls can be forwarded to any defined telephone number. Your customers enjoy shorter waiting times while your business benefits from greater availability. Calls are forwarded within the core network and not only in the voice system at the customer site. So calls are not lost, even if the voice system fails.

Emergency calls are forwarded from your private branch exchange to the nearest emergency call centre according to the location information of the emergency call function (E112 standard).

Spoofing has also become common in telephony. Callers transmit a telephone number (caller ID or A number) for which they have no usage rights. For example, as the caller ID, callers use a Swiss number that is assigned to an end customer (police, hotline, company number, etc.) or that has not yet been assigned. Both are clear cases of misuse.

Spoofing poses a danger because the callers are assuming a false identity and the calls are answered because of the deception. The callers often have fraudulent intentions. It is also possible that customers whose phone number has been misused could receive annoying call backs despite not being responsible for the original call. A company or authority’s reputation could be damaged by this.

The Anti-Spoofing option for Enterprise SIP allows organisations to protect their phone numbers. To do this, they configure the option for each number block individually in the Enterprise SIP application in My Swisscom Business, directly within the Swisscom network. The option is configured for entire number blocks rather than individual numbers.

There are different availability options that can be selected, depending on customer requirements:

• Monthly availability of up to 99.9%
• Multi server (1 PBX, multiple servers)
• Multiple service access points (geographically dispersed PBX)
• Multi PBX (multiple PBX at one site)
