I am starting a new topic because I don’t seem to be getting any bites on the last one (Extremely poor recording quality - Asterisk 11). My issue is that I have 2 SIP trunk devices. They are both from the same company, the only real difference is one accepts 8 sim cards, the other 44.
In either case, the audio quality of the phone calls are great, but when recording anything while using the new 44 slot device, the quality is terrible. This is really confusing to me. How can my call sound great, but the recording not?
It is easy to blame the device (http://www.openvox.cn/products/voip-gateways/210/64/3g-gateway/vs-gw2120-3g-series-1-detail.html), but from the call quality, it seems like it is doing it’s job correctly, it seems like an Asterisk / sox issue, but not sure what to troubleshoot there.
I am using Asterisk 11 from the latest free Elastix version on a Dell R610 w/ 16GB RAM.
