[opus] Question on opus_decoder output sampling rate

Hi, is there any way to tell the decoder the output sampling Fz we want ?
opus_decoder_create = Sampling rate of input signal (Hz)
Considering this example (VoIP-out from WebRTC/RTP)
MICROPHONE(44.1/48kHz) >> [encoder created at 48kHz but with
internalSampleRate set to 8kHz]>> INTERNET >> [decoder(created with 48kHz)]
>> 48kHz(?) >> G.711(8kHz)
This leaves us with the only option to re-sample even if the internal
sample rate was set to 8kHz.
This may not seem like a big problem since we could simply resample but on
a server with a lot of load this could be significant ?
Is not very clear on these points.
