As far as I know Asterisk is the only router that does transcoding
between call legs including both media and signaling. I have tested
only SIP to H323 (GSM to G711).
Cisco will support transcoding beginning with Q3 for 2621XM family
(between G729 and G711).

Does anyone know of a media proxy that will transcode between g.711 and
iLBC?
Thanks,
