Release Notes for Tieline G3 Firmware v.1.6.72 RPTP 104

From the 31st March 2011 Tieline has discontinued support for the Voice G3 algorithm. As a result it has been omitted from this v.1.6.72 firmware release and all codecs purchased after this date. Codecs with firmware v.1.6.72 or higher can connect to G3 codecs running older firmware versions, but will have to use an algorithm other than Voice G3. Voice G3 is usually used for low-bitrate connections over GSM and POTS. We recommend using Tieline Music as a substitute for these low bit-rate connections.

  1. It is now possible to configure a ‘Hangup Profile’ in G3 codecs. This means a codec can receive calls from other codecs that change its existing connection profile, and then the codec receiving the call will automatically return to the preprogrammed Hangup Profile after disconnection. Program this via [Menu] > [Configuration] > [Advanced] > [Hangup Profile] and select the profile.
  2. A new version of Toolbox v.4.14.48 is now available on the firmware download page to support firmware release v.1.6.72.
  3. TLR300B2 codecs now support 256Kbps MP2 J-Stereo connections at 32KHz and 48KHz sampling over IP and X.21.
  4. References to “RAW” uncompressed data are now renamed “PCM” in G3 codecs for consistency with new Tieline codecs.
  5. Telstra 3G Wireless Access Points have been renamed for Australian customers.
