SIP Provider i4IP (NL)

I4IPis offering a SIP trunk with user authentication. You have received information about UserID, UserName and UserPassword, whereas the naming may differ, or you might have only received UserName and -password. In this case, UserID and UserName are identical.

Configuration

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.

I4IP is offering the possibility to configure the SIP Trunk on the provider side via a web interface. Please be aware that changes in the settings must be reflected by the SwyxWare setting and adopted accordingly.

For FAX transmission via T.38, I4IP is offering separate SIP trunk. If this is required, a separate SIP trunk group must be created and a corresponding SIP trunk. For the trunk group, the routing record must have a higher priority than the one f the other trunk group. Additionally, the FAX User must be configured as exclusive user for that trunk group.

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: +31 36 1234560 ... +31 36 1234569

Important: From SwyxWare 11.50.0.0 on, the provider profile for i4IP is already available in the list of provider profiles and the CustomProviderProfiles.config is no longer necessary.
