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.
