I'm using Asterisk 1.8.13, FreePBX 2.11,<br>> chan_capi 1.1.6.<br>> <br>> Everything works great, I can place outgoing calls, ingoing calls work,<br>> internal calls too, voicemail, ...<br>> <br>> The only problem is the audio quality when using chan_capi to place<br>> calls. The remote party can not hear me clearly and from the
asterisk<br>> side, I hear a clicking noise (I can try to record it if that helps)<br>> repeating at close intervals but only when someone is speaking or when<br>> there's music (basically, when there is no silence).<br>> <br>> I've skimmed Google for answers and came up with some old posts dating<br>> back to 2003/4/6/... speaking about the CAPI_MAX_B3_BLOCK_SIZE value in<br>> chan_capi.h. I tried to tweak that value and recompile several times.<br>> Each time, I have the same clicking noise but the interval changes. I<br>> can't get rid of the noise though.<br>> <br>> This is currently preventing me from putting my setup in production and<br>> I'd really like to find a solution for this.<br>> <br>> I'll be glad to hear any pointers you can throw at me. I can basically<br>> try everything as this is not in prod yet.<br>> <br>> Thanks a lot in advance!<br>> <br>> -- <br>> Léopold
