Issue Description

We should judge the speed parameter setting whether meet H221 protocol when we hold or schedule a conference, or we may fail.

Alarm Information

Wong speed

Handling Process

Examine the MLP, LSD and audio speed settings of each port to meet the following relation:
a, If MLP speed is 0, LSD speed is one of 0, 0.3k, 1.2k, 4.8k, 6.4k, the audio speed must be one of 32k,40k,48k,56k.
b, If MLP speed is 0, LSD speed is one of 8k,9.6k,14.4k, the audio speed must be one of 32k,40k,48k.
c, If MLP speed is 4k, LSD speed is one of 0,0.3k,1.2k, the audio speed must be one of 32k,40k,48k,56k.
d, If MLP speed is 4k, LSD speed is one of 8k,9.6k, the audio speed must be one of 32k,40k,48k,56k.
e, If MLP speed is 6.4k, LSD speed is 0, the audio speed must be one of 32k,48k,56k.
f, If MLP speed is 6.4k, LSD speed is 8k, the audio speed must be one of 32k,48k.
g, If MLP speed is 8k, LSD speed is one of 0, 0.3k, 1.2k, 4.8k, 6.4k, the audio speed must be one of 32k,40k,48k.
h, If MLP speed is 14.4k, LSD speed 0, the audio speed must be one of 32k,40k,48k.

Root Cause

The summation of the speed settings of audio, LSD, MLP and HMLP larger or equal to transmission speed is an error.
