Hi Group, actual i have a transcode problem and i have no idea to solve this. All my wav files are alaw encoded and i allow only alaw codec. But sometimes the WriteFormat is slin and if i recall the same number the WriteFormat is alaw for the Channel. Why the channel has sometimes slin and sometimes alaw? NativeFormats: 0x8 (alaw) WriteFormat: 0x40 (slin) ReadFormat: 0x8 (alaw) WriteTranscode: Yes ReadTranscode: No After this I'm going into a conference Room and the Format completely change to slin. NativeFormats: 0x8 (alaw) WriteFormat: 0x40 (slin) ReadFormat: 0x40 (slin) How can i change the Format for Meetme to alaw which is the NativeFormat. Thanks for your help. Daniel PS: i unload the format_sln16.so and format_sln.so modules. -------------- next part -------------- An HTML attachment was scrubbed...
