老大評論,受寵若驚
OBiOn 1.2.0(2291)以上可選如下不同通話質量:
Audio Codec: Best-64, Great-32, Good-24, or Acceptable-16 kbps
Google Talk 有如下 codec:
5. Which voice codecs do you support?
Today, Google Talk supports the following standard voice codecs:
- PCMA
- PCMU
- G.722
- GSM
- iLBC
- Speex
We also support the following codecs from Global IP Sound: ISAC, IPCMWB, EG711U, EG711A.
其中有些bandwidth較低。G729可能有版權費,Google不願交。
總之OBiOn網上評論還比較差。通話質量是一個(可試一下低一點的Audio codec)。另一個是耗電大(不知下個版本本能否改進,CSipSimple用TCP可改進)。
