Hi all, im my current test-environment, I want asterisk to play a wav-file as a response to a g.726-32 call
extensions.conf exten => 2000,1,Answer() exten => 2000,n,Playback(some_sentence) exten => 2000,n,Hangup() When I play the wave-File with mplayer, I am getting the following file-information: Audio file file format detected. ========================================================================== Forced audio codec: mad Opening audio decoder: [pcm] Uncompressed PCM audio decoder AUDIO: 8000 Hz, 1 ch, s16le, 128.0 kbit/100.00% (ratio: 16000->16000) Selected audio codec: [pcm] afm: pcm (Uncompressed PCM) ========================================================================== AO: [alsa] 48000Hz 1ch s16le (2 bytes per sample) Now, when activating the G.711 alaw in the calling client, everything is working fine, I can create the call to the * and I get the sentence played correctly. But when I create a SIP-call to the *PBX, where only G.726-32 is allowed as RTP-codec on the caller, the call is also received, but I only get random noise. Well, as I had no clue, what to do, I tried to convert the wav-file to g726-32 explicitely with the asterisk-"convert" command: file convert /usr/share/asterisk/sounds/some_sentence.wav /usr/share/ asterisk/sounds/some_sentence.g726-32 As a result, I got the following error: Failed to convert /usr/share/asterisk/sounds/some_sentence.wav to /usr/share/asterisk/sounds/some_sentence.g726-32! [Oct 19 16:13:54] WARNING[8846]: format_g726.c:166 g726_write: Invalid data length 69, should be multiple of 40 [Oct 19 16:13:54] WARNING[8846]: file.c:209 ast_writestream: Translated frame write failed I do not know, if this error is related to the problem described above.
