...l sounds as good as POTS, but the audio quality in the inbound direction (outside world -> VoIP Provider -> asterisk -> softphone) is noticeably worse. It sounds "overcompressed" or "slightly robotic" somehow, with a decrease in dynamic range. It's not lagged or echoey; it just sounds like it's maybe using a crappier codec than ulaw, in that direction only. I'm baffled by this. Both legs of the calls show as "Format: 0x4 (ulaw)" in "sip show channel". Testing the first provider, I just assumed that their analog->digital co...

Before I relate the actual problem, some context. Callcentre environment, a few users testing a new digital dialer... 1. Agents are using Grandstream ATA HT486 and a small analogue dialpad with a headset. 2. SIP connection to Asterisk-1.2b1 3. IAX2 connection to ITSP provider. The call is initially set up in the following way. 1. Agent calls into a meetme conference room and subseqently stays

...lder versions (0.7.1) a pointer to NULL did the trick, but with code from the tip of the GIT repository, this method causes the codec to crash on the C55x fixed point platform. I have not determined where the crash occurs. I have also attempted to pass in an array of zero's and this creates an echoey, reverby effect, but does not have any loud, full-scale artifacts. Is this the correct method for calling PLC? This does not sound nearly as good as the samples on the website. Also, while I am here, I thought I would ask if any CELT enthusiasts are migrating over to the OPUS code base? My main a...
