Hi,

I would like to know more over the transcoding function with asterisk.
How exactly works asterisk, in order to transcoding?
Where I can get exactly informations?
If asterisk transcodes, for example ilbc to gsm, how can I see which
(ilbc)rtp-packet becomes which (gsm)rtp-packet? I use the ethereal protocol
analyzer.
Apology for my English.

Best regards
George
