SIP Provider gnTel (DE)

General

The SIP Trunk from gnTel was first tested and released with SwyxWare 12.30.0.0.

The SIP Trunk from gnTel is a SIP Trunk with user authentication, i.e. you receive information on user ID, user name and password. The names may differ, or you may only receive a name or ID with password. In this case the user ID is identical to the user name when configuring the SIP trunk in SwyxWare.

Platforms 

SwyxWare
The SIP Trunk from gnTel can be used from SwyxWare 12.30.0.0 on. When using an earlier version of SwyxWare incompatibilities cannot be excluded and use is at your own risk.

SwyxON
The SIP Trunk from gnTel is not released for central connection in the data center.

Configuration 

When creating the SIP trunk group, select the profile 'gnTel (DE)'. If the profile is not included in the corresponding list, you can download the required CustomProviderProfiles.config for SwyxWare at the end of this article. For more information about using this file, see Configuration and Adaptation of SIP Providers via Provider Profiles.

SIP URIs

When creating the actual SIP trunk, a SIP URI must be entered after entering the phone number range so that incoming calls can be assigned. The assigned number block must be taken into account in the correct format.
Example:
Number block: +49 211 99887760 ... +49 211 99887769 In this case, the SIP URI must be entered in the format +492119988776*@*.

Codec Configuration

During creation of the actual trunk, in the codec configuration dialog, T.38 has to be deselected as supported codec. This step could also be performed afterwards in the properties of the SIP trunk, underneath the 'Codecs' tab.

• Incoming/outgoing national calls
• Correct Calling Line Identification (CLI) on national calls
• Holding and retrieving calls
• CLIP-No-Screening
• Toggeling between two calls
• Call transfer
• Conferencing
• Mutually supported codecs: G.711a/ G.711u
• Incoming/outgoing DTMF signaling in accordance with via RFC2833
• FAX transmission via G.711

Restrictions:
None

Test date:
12/01/2021 with SwyxWare 12.30.0.0

Disclaimer

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.
