Hello, 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:
7.590966] Zapata Telephony Interface Registered on major 196 [ 7.590966] Zaptel Version: 1.4.12.1 [ 7.590966] Zaptel Echo Canceller: MG2 [ 7.610963] zttranscode: Loaded.

I am trying to do 2 experiments: 1) asterisk1 --->g729--> asterisk2 (with transcoding card) Playfile in ulaw format 2) asterisk2 --->ulaw--> asterisk2 (with transcoding card) Playfile in g729 format In the first case I get all calls proceeding and in asteris2 cli Connected to Asterisk 1.4.23.1 currently running on katerin (pid = 3168) Verbosity was 3 and is now 5 katerin*CLI> transcoder show 90/0 encoders/decoders of 92 channels are in use. But it all does not work for the second case, in asterisk2 cli I get messages like [Feb 19 15:18:32] ERROR[3121]: codec_dahdi.c:244 zap_translate: Unable to attach to transcoder: Input/output error [Feb 19 15:18:32] WARNING[3121]: translate.c:294 ast_translator_build_path: Failed to build translator step from 8 to 2 [Feb 19 15:18:32] WARNING[3121]: chan_sip.c:3751 sip_write: Asked to transmit frame type 256, while native formats is 0x4 (ulaw)(4) read/write = 0x4 (ulaw)(4)/0x100 (g729)(256) Btw call does go through but transcoding is done by processor not by TC400P. Did anyone encounter such problem?
