EmslandTel.net is offering SIP trunks with and without user authentication. The tested SIP Trunk is without user authenication, this means that the authentication is based on the public IP address of the SwyxWare server. Therefore, you need a static, public IP address from your ISP.
For your convenience the generated CustomProviderProfiles.config is available for download at the end of this article. Extended information about how to use this file can be found at Configuration and Adaptation of SIP Providers via Provider Profiles.
During creation of the SIP trunkgroup, profile'ETN VoIP (DE)' has to be selected.
Important: In case that the SwyxWare server is running with a private IP address and the static, public IP address is provided by NAT gateway, it is necessary to configure a STUN server in the properties of the SIP trunk group, under the tab 'SIP'. A list of public STUN servers can e.g. be found at http://www.voip-info.org/wiki/view/STUN. In this case, it is necessary to configure the correct portwarding in the NAT gateway, such that inbound SIP requests are being forwarded to port 65002 of the SwyxWare server.
If no NAT gateway is necessary, the provider has to be consider that inbound SIP requests are being directly sent to port 65002 of the SwyxWare server.
