The Smart Business Connect Trunk (SBCon) from Swisscom was first tested and released with a SwyxWare 2015 R3.
On behalf of the customer, the partner orders the Smart Business Connect trunk (SBCon) from Swisscom. Swisscom will deliver an appropriate gateway with eSBC functionality (Cisco 881 or Cisco ISR 4321). This eSBC will act as a SIP trunk for the SwyxWare and performs the call signaling towards the Swisscom. A profile for the SwyxWare ist installed on the eSBC which is synchronized with the SwyxWare configuration.
For the connection from the SwyxWare to the eSBC, it must be assured that the eSBC in the customer's network is configured with a static IP address.
The Smart Business Connect Trunk from Swisscom can be used without restrictions from SwyxWare 2015 R3 on. When using an earlier version of SwyxWare incompatibilities cannot be excluded and use is at your own risk.
Because of the dependency from the locally installed eSBC, using the Smart Business Connect Trunk (SBCon) from Swisscom in a SwyxON environment is not supported.
- Creation of a location with the information of the assigned number range
- Creation of a SIP trunk group with the Swisscom SBCon profile "Swisscom_SBCon (CH)"
- In the properties of the SIP trunk group, within the tab "SIP", the IP address and if necessary, the port of the eSBC have to be configured in the field "Registrar" and in the field "Proxy"
- Creation of a SIP trunk underneath the newly created SIP trunk group
- Enter user credentials for registration
- Configuration of the assigned number range
In the SIP trunk properties, underneath the tab “Codecs/Channel”, the option “Remove T.38 from initial invite” has to be selected.
Note: In case that FAX transmission has to be carried out through G.711 exclusively, T.38 has to be deselected in the list of supported codecs.
At the end of this article, you find a recommendation from the Swisscom about handling of analogue FAX machines.
CLIP No Screening
To activate feature CLIP No screening, in the tab 'Number Signaling' of the trunk properties the option 'Always use originator's number' must be set.
- Incoming/outgoing national calls
- Incoming/outgoing international calls
- Correct Calling Line Identification (CLI) on national and international calls

Verifying interoperability between different SIP providers and the Swyx solution is part of the Enreach Technology Alliance Programme (TAP) tasks. Due to different implementations of the SIP RFCs, it is necessary to determine and provide an individual configuration for each SIP provider.
Within the TAP, Enreach tests a large number of national and international SIP providers in order to make statements about the interoperability with the Swyx solution and the functional scope of the respective SIP trunk. These results and, if needed, configuration advice are published in Help Center articles.
Enreach is in close contact with selected SIP providers to ensure a quick troubleshooting in case of incompatibilities. In addition, tests are repeated at regular intervals to ensure consistent quality.
Despite regular retests it cannot be excluded that incompatibilities with the Swyx solution may occur due to changes in the SIP connection on the provider side or that the provided profile is no longer valid. After creating the trunk group or SIP trunk, the profile settings should be compared with the provider's information and adjusted accordingly in case of deviations.
However, should incompatibilities or problems occur with a tested SIP trunk, no claims for recourse against Enreach GmbH can be derived from this. In such cases, you can contact Enreach Support via your specialist dealer.
