For IAX2, at least, Asterisk oes not use the lost-packet-concealment of any codec. This is because the incoming frames "clock" Asterisk. For iLBC's lost packet concealment to work, Asterisk would have to start calling the decoder with a NULL at the point when the missing packet shold have arrived. Can't say for sure for SIP, but I'd guess that its the same.
