SIP Provider NetCom BW (DE)

The SIP trunk of NetCom BW was first tested and released with SwyxWare 11.20.0.0.

The actual connection to the SIP trunk of NetCom BW is made via a separate SBC. SwyxWare itself connects to the SBC via a registerless SIP trunk. The static, local IP address of the SBC is required for configuration. The SBC must be configured to address port 65002 of SwyxWare Server as SIP endpoint and not the default SIP port 5060.

The actual interoperability tests were performed by NetCom BW itself, not by Swyx.

Platforms 

SwyxWare:
The SIP Trunk of NetCom BW can be used without restrictions from SwyxWare 11.20.0.0 on. When using an earlier version of SwyxWare incompatibilities cannot be excluded and use is at your own risk.

SwyxON:
Not supported

Configuration 

When creating the SIP trunk group, select the profile'NetCom BW (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).

Because of the connection to the SBC it is not possible to pre-assign the entry for the registrar / proxy server in the "SIP" tab in the properties of the trunk group. The IP address of the SBC must be entered here after the trunk group has been created.

When creating the actual SIP trunk, all audio codecs except G.711 can be deselected  in the codec dialog. T.38 as supported codec must be deselected.
