5.5. Voice Configuration

Codec Priority

Set the Codecs priority here. If you set the g723 at first priority,

g729a at second priority, then the gateway will use g723 to

negotiate the connection first, then shift to second codec if the

first didn’t match

Frame Size

Set Specify sending packet size, G.723: 30/60/90, G.711A,

G.711U, G.729: 20/40/60/80ms, G.729A: 20/40/60/80ms. The

smaller the packet size, the shorter the delay time. If network is

in good condition, smaller sending packet size is recommended

G.723 Silence
