6.what kinds of voice codec can be selected for TCL-IP8? 
Answer

The default voice codec of TCL-IP8 is 

PCMU(G.711u).PCMU and PCMA both can supply better quality 
voice

but possess a big bandwidth which is up to 64kbps.If the 

network bandwidth is lower

you should select another lower Bit rate 

voice codec

for example: G.723 or G.729, which possess the lower 

bandwidth than the others(G.723 only for 5.3K/6.3K,G.729 for 8K)

and also can get better quality voice .If bandwidth is enough, select 
PCMU or PCMA

or even G.722    (G.722.1 can supply perfect 

quality voice) will be better.
