It sounds like you just don't have enough throughput in the one direction.  
Voicemail is fine because it doesn't need "realtime" capacty - the voice 
frames arriving from your side go into the captured file as they arrive, 
doesn't matter if your 10 second message takes 20 seconds to arrive...

You could try using a lower bandwidth codec like GSM if you aren't 
already.
