Hi!
I have the CUBE router recieving h.323 calls from Provider, codec is g729. I need to configure IVR(vxml) support on this router on incoming calls, IVR uses g711alaw codec. How should I configure DSP resources for this task?
I have read about universal transcoding and here is my config:
/*
voice-card 0
no dspfarm
dsp services dspfarm
...
voice service voip
allow-connections h323 to h323
...

Although DSP profiles are registered, but they are not beeing activated while calls ocure. The calling party hears fast busy.

Does 'show sccp' show them as registered?
And are you sure you're running into a codec problem (cause=47) and not some other problem causing fast busy?

I faced this transcoding issue and changing IOS to Version 12.4(15)T8 resolve it.
Original IOS version was 12.4.11 T3.
