The Business Voice SIP Trunk from T-Mobile Austria was first tested and released with a Swyxware 12.00
T-Mobile Austria is offering the Business Voice 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. Besides, you need an IP address which was assigned by UPC and which gets connected to the SIP trunk.
The actual interoperability tests were performed by the company data-way, not by Swyx TAP.
The Business Voice SIP Trunk from T-Mobile Austria can be used without restrictions with SwyxWare 12.00 or higher. When using an earlier version of SwyxWare, incompatibilities cannot be excluded and use is at your own responsibility.
The Business Voice SIP Trunk from T-Mobile Austria is not suitable for central connection in the data center due to its dependence on the assigned IP address.
Numberblock: +43 662 1234560 ... +43 662 1234569
In this case, the SIP URI must be entered in the format 0662123456*@*.
On outgoing calls T-Mobile Austria changes some characteristica of the RTP stream call setup and call answering. This may lead to a oneway voicechannel if internal encryption is active. Therefore, in the tab "Encryption" of the SwyxServer properties, you have to deactivate internal encryption.
Exclude G.722 in the Codecs/Channel tab of the Trunk Properties dialog.
