Overview
Vortex CallMe-TS Studio Codec
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-TS Studio Codec has been designed as a hardware back-end for CallMe Click-and-Connect™ - Vortex's internet codec service which lets guests and reporters send high-quality low-delay audio back to the studio without the need for them to have their own IP codec or download special software. Apart from CallMe-TS, CallMe Click-and-Connect™ is of course compatible with most IP Audio Codecs too. CallMe-TS has balanced stereo inputs and outputs on ¼" Jacks plus RJ45 Ethernet connectivity, now with USB Audio Interface.
