[Spce-user] No sound with outbound call

[j.feugne at prisnets.ch]

hello,
I'm just starting with Sipwise and I've setup a VM running version 
mr4.1.1 CE.
I have followed the instructions of the manual and all subscribers can 
call each others.
I also setup a sip peer to voicetrading, and here is waht I have withthe 
command line ngrep sip on my vm while placing and outband call:
NB, voicetrading is expecting for premium rate all number to be leading 
with 00000 (5 zero)
