Wide range of supported voice codec |
|
SyncSwitch offers multiple codec support to meet interoperability, compression, and latency requirements for various phone-to-phone and PC-to-phone applications: G.711 (alaw & ulaw), ADPCM, SLIN, LPC10, SPEEX, ILBC, G.722 G.723.1 (5.3K and 6.3K), G.726, G.726aa12, G.729ab, GSM, H.261, H.263, H263p, and H.264. The same number of calls is supported across all codec types to simplify network engineering. Enabling voice activity detection (VAD) reduces packet traffic through the network. With VAD enabled, the Sync Switch detects silence and stops transmitting packets when callers stop speaking. Variable frame sizing provides further control over voice packet.
