Summary

Information und configuration hints for SIP provider DNS:NET (Germany)


Information

General information

The SIP Trunk from DNS:NET was first tested and released with SwyxWare 11.32.0.0.

The SIP Trunk from DNS:NET 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.

Plattforms

SwyxWare: The SIP Trunk from DNS:NET can be used from SwyxWare 11.32.0.0 on. When using an earlier version of SwyxWare incompatibilities cannot be excluded and use is at your own risk.

SwyxON: The SIP Trunk from DNS:NET is suitable for central connection in the data center.

Configuration

When creating the SIP trunk group, select the profile 'DNS:NET (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 (kb3436).

SIP URIs
In order to assign incoming calls to the correct trunk, it is necessary to configure a SIP URI for the trunk. The assigned number block and the numberformat must be considered.

Example
Numberblock: +49 40 1234560 ... +49 40 1234569
In this case, the SIP URI must be entered in the format 4940123456*@*.

Afterwards, the LinkMgr service has to be restarted.

STUN
A connection to DNS:NET trunk requires a STUN server, which is provided by DNS:NET themselves. This STUN server uses the default port 3478. The networking environment (NAT, firewall) has to allow communication with that port.

NAT
To avoid the NAT binding time-out problems, one of the two solutions has to be applied:

  1. Increasing the UDP timeout on the NAT gateway to a greater value than the registration interval of 180 seconds.
  2. Activating the keep-alive packets with a time interval less than the UDP timeout of the used NAT gateway. The actual value depends on the NAT gateway configuration.
    Use the following power shell cmds to activate the sending of the keep-alive messages. In this example, the keep-alive messages will be sent every 30 seconds.
    Connect-IpPbx
    Set-IpPbxGlobalConfigItem -Section "Server" -SubSection "LinkMgr" -Key "KeepAliveTimeout" -Value 30
    Disconnect-IpPbx

    Afterwards, the LinkMgr service has to be restarted.
    Important: These setting will affect all SIP trunks.
