This chapter only summarizes recommended values and settings. To access the Barix Instreamer web-based configuration interface simply point your internet browser to Instreamer IP and choose Settings from the menu above. Then select one of sub-menus and check or change these settings:

Network

Under Settings > Network localize the parameter IP address and write it down – it will be used for defining the captured stream (parameter streamUrl). It is recommended to assign a static IP address to every Instreamer in your network or at least to reserve this IP address in the DHCP server.

Audio

The next tab contains audio settings for the stream. Nearly all parameters may stay set as the default values, but two of them are recommended to be set this way:

  • Sampling frequency – there are lots of different settings and some of them are a little nonstandard (and causes problems while played in Windows Media Player). There are two recommended values – MPEG2/24kHz and MPEG1/32kHz. Setting 16kHz and 22.5kHz causes problems in Media Player, while setting 44.1kHz and 48kHz means higher quality than the telephone call itself has (and is useless).
  • MP3 Emphasis = none – because the audio signal will be recorded by Call Recording, it is not necessary to use this feature.

Streaming

This determines the way the stream will be broadcast to the network. There are four important settings:

  • Radio Path – is used for defining a captured stream (parameter streamUrl), you should write it down for later use.
  • Stream Packet Strategy – is recommended to be used in lowest latency mode to ensure real-time recording.
  • Streaming mode – determines how to stream audio data. There are three settings and it is recommended to use the send on Level feature:
    • send always – will stream always, in this case carefully set the maxSilence parameter in Instreamer module configuration file to prevent the overfill of your Storage server.
    • send on CTS - will stream if the Send button is pressed or serial connector is connected, there is no need of changes in configuration of Instreamer module.
    • send on Level – the same as before, but instead of streaming being based on button pressing, it will be based on the presence of incoming audio signal, this is the recommended configuration. If you use this setting, you may need to change value of the Trigger Level to a value corresponding with level of noise of your Instreamer <-> Device connection and volume level of recorded device (but in most cases the default value 1000 will be optimal).
  • Shoutcast stream has to be set to public. If set to private, Call Recording will not able to record the stream.
