to define packet size for each codec. 20/40/60ms means to send | |
| a voice packet per 20/40/60 milliseconds. The smaller the |
| packet size, the shorter the delay time. If network is in good |
| condition, smaller packet size is recommended. In this |
| parameter, 20/40/60ms is applicable to G.711u/a law, and |
| G.729a codec, while 30/60ms is applicable to G.723.1 codec. |
codec priority while negotiating with other h323 device. This | |
| parameter determines the listed sequence in h.245 TCS |
| message. The codec listed in left side has the highest priority |
| when both parties determining final codec. |
There are three adjustable value. Voice volume stands for | |
| volume which can be heard from VoIP FXO gateway side. Input |
| gain stands for volume which the opposite party hears. Dtmf |
| volume stands for DTMF volume/level which sends to its own |
| Line1 or Line2. |
