Hello,<br>
<pre>I have transcoding card TC400P installed in server running Debian with Asterisk 1.4.23. Everything seams to be fine and after I boot up server I see in dmesg:<br><br> 7.590966] Zapata Telephony Interface Registered on major 196<br>

<br>In the first case I get all calls proceeding and in asteris2 cli <br><br>Connected to Asterisk 1.4.23.1 currently running on katerin (pid = 3168)<br>Verbosity was 3 and is now 5<br>katerin*CLI> transcoder show<br>90/0 encoders/decoders of 92 channels are in use.<br>
<br>But it all does not work for the second case, in asterisk2 cli I get messages like<br><br>[Feb 19 15:18:32] ERROR[3121]: codec_dahdi.c:244 zap_translate: Unable to attach to transcoder: Input/output error<br><br>[Feb 19 15:18:32] WARNING[3121]: translate.c:294 ast_translator_build_path: Failed to build translator step from 8 to 2<br>

Did anyone encounter such problem?<br>
