[Asterisk-Users] Transcoding

[Martin Sutherland]

I though that Asterisk would transcode between codecs! All my SIP devices support G729a & 711a/u but my ISDN PRI/BRI lines use 711a/u. Asterisk is quite happy to accept a call from a SIP device using G729a and then complains that it can't translate into G711 to go onto the ISDN network. Does anybody know if there is some setting somewhere or if this is how it is supposed to work
