Information und configuration hints for SIP provider Alphalink (France).


Informazioni

General information

Alphalink is offering SIP trunks with user authentication and registerless SIP trunks. The authentication for a registerless SIP trunk is based on the public IP address of the SwyxWare server. Therefore, you need a static, public IP address from your ISP assigned to the SwyxWare server. For a registerless SIP trunk, it is not possible to run the SwyxWare with a private IP address behind a NAT gateway with a public IP address.
If you are running the SwyxWare server behind a NAT gateway, you need a SIP trunk with user authentication.  You have received information about UserID, UserName and password. Even for a SIP trunk with user authentication, Alphalink additionally checks the public IP address, but in this case, it could be the public IP address of a NAT gateway.

Alphalink is operating with a number of different servers. Therefore it is not possible to preconfigure the Proxy Server in the "SIP" tab of the Trunkgroup properties. In this field, please enter the IP address or server name that Alphalink has named you.

 

Configuration

For an AlphaLink SIP trunk with user authorisation, it is necessary to configure a SIP URI for the trunk in order to assign incoming calls to the correct trunk.

Example
Assigned number range: +33 970 1234560 ... +33 970 1234569. Since Alphalink is signalling the destination number in the request URI in format canonical without plus, the SIP URI for the trunk must be configured as '33970123456*@*'.
 
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 (kb3436).

Important: From SwyxWare2013 R4 on, the provider profile for Alphalink is already available in the list of provider profiles and the CustomProviderProfiles.config is no longer necessary.
