Hi, I got a weird issue when I dialed an extension and listen to a recorded voice mail greeting message. After playing a couple of time of the greeting, the FS printed the warning of "sample rate not matching", then send the audio to a different remote RTP port. See the log below, 2009-12-02 12:42:27.109529 [DEBUG] switch_ivr_play_say.c:1097 Codec Activated L16@16000hz 1 channels 20ms 2009-12-02 12:42:27.112038 [DEBUG] switch_core_io.c:649 sofia/internal/1003@xxx.yyy.zzz.31 receive message [TRANSCODING_NECESSARY] 2009-12-02 12:42:28.86119 [DEBUG] switch_ivr_play_say.c:1391 done playing file 2009-12-02 12:42:28.205975 [DEBUG] switch_ivr_play_say.c:118 No language specified - Using [en] 2009-12-02 12:42:28.220967 [DEBUG] switch_ivr_play_say.c:273 Handle play-file:[voicemail/vm-record_message.wav] (en:en) 2009-12-02 12:42:28.222971 [DEBUG] switch_ivr_play_say.c:1097 Codec Activated L16@16000hz 1 channels 20ms 2009-12-02 12:42:28.222971 [DEBUG] switch_core_io.c:649 sofia/internal/1003@xxx.yyy.zzz.31 receive message [TRANSCODING_NECESSARY] 2009-12-02 12:42:32.804858 [DEBUG] switch_ivr_play_say.c:1391 done playing file 2009-12-02 12:42:32.944554 [DEBUG] switch_core_io.c:649 sofia/internal/1003@xxx.yyy.zzz.31 receive message [TRANSCODING_NECESSARY] 2009-12-02 12:42:33.946969 [WARNING] switch_core_file.c:120 Sample rate doesn't match 2009-12-02 12:42:33.950231 [DEBUG] switch_ivr_play_say.c:549 Raw Codec Activated 2009-12-02 12:42:34.124584 [INFO] switch_rtp.c:1869 Auto Changing port from xxx.yyy.zzz.39:10002 to xxx.yyy.zzz.39:1748 2009-12-02 12:42:34.944913 [DEBUG] switch_core_codec.c:122 Restore original codec. 2009-12-02 12:42:34.947918 [DEBUG] mod_voicemail.c:1162 Message is less than minimum record length: 3, discarding it. 2009-12-02 12:42:34.947918 [DEBUG] switch_ivr_play_say.c:118 No language specified - Using [en] 2009-12-02 12:42:34.960002 [DEBUG] switch_ivr_play_say.c:273 Handle play-file:[voicemail/vm-too-small.wav] (en:en) 2009-12-02 12:42:34.960850 [DEBUG] switch_ivr_play_say.c:1097 Codec Activated L16@16000hz 1 channels 20ms 2009-12-02 12:42:34.960850 [DEBUG] switch_core_io.c:649 sofia/internal/1003@xxx.yyy.zzz.31 receive message [ the original codec is wideband 16kHz Speex and the wireshark shows that the FS used the same codec. I used FS 1.04 in fedora 8. I have two questions here, (1) why does FS report "Sample rate doesn't match"? is it a bug or configuration issue? (2) Why does FS change the RTP port ? how to fix it? Thanks, Regards,
