Overview
Vortex CallMe-TR Studio Codec with Quickdial Buttons
CallMe-T is a small-size, low-cost IP Audio Codec supporting Opus/G.722 audio coding algorithms with balanced stereo audio inputs and outputs on ¼" Jacks plus RJ45 Ethernet connectivity, now with USB Audio Interface. It is housed in a 108mm x 103mm x 44mm enclosure for table-top use whilst for larger installations, 4 can be mounted side-by-side in 1-U. CallMe-T (as in "ET - phone home") was originally designed as a low-cost hardware back-end for CallMe Click-and-Connect but as a result of customer requests for an add-on for ISDN Mixers to allow their use over IP, there are now two versions: CallMe-TS designed for standalone Studio use with remote control via its web interface and CallMe-TR designed for Remote use which has dedicated "Quick Dial" buttons to make and disconnect calls to other codecs - in addition to the web interface.
CallMe-TR has the same capabilities as CallMe-TS but additionally has programmable Quick Dial buttons on the front panel to avoid the need to use the web interface. It supports Opus/G.722 audio coding algorithms with stereo audio inputs and outputs on ¼" jacks plus RJ45 Ethernet connectivity. Two cables are needed to connect to the ISDN mixer; balanced audio from the codec plugs into the Cue input of the mixer and the Mixer Output connects to the audio input of the codec. As a hardware codec, CallMe-TR provides improved reliability and robustness compared with using software devices, making it the ideal IP connectivity solution for the hundreds of ISDN mixers still in use today.
CallMe-TR has the same web interface as CallMe-TS Studio Codec, providing complete flexibility to manage connections.
