[Asterisk-Users] Transcoding

[Thomas Jalsovsky]

Hello,

	Does asterisk do transcoding when the call goes
through the system, codecs are the same but signaling protocol is changed.
example:
SIP with GSM ---> IAX with GSM

	What quality destruction happen when I use transcoding? I know
this is not a concrete/precise question, but I would like to know how is
it in general.

	What CPU performance is needed for transcoding 30 channels e.g.
from GSM to g723.1 in general?

	Thanks in advance,
		Thomas
