[cisco-voip] Transcoding on Cisco 2901

[Robert Hass]

Hi

I've got Cisco 2901 with two dial-peers:
1) H.323, codec G.711 u-law
2) SIP, codec ILBC

This Cisco have to transport voice from H.323 trunk do SIP trunk with
transcoding between G.711u and ILBC.
But I'm not sure how to configure transcoding within dial-peers.
Router has PVDM3-64.

I have configured:

voice-card 0
 dspfarm
 dsp services dspfarm

but it's look that is not all what is needed to have transcoding
between dial-peers

Any hints ?
