[Spce-user] Cannot place outbound calls from a subscriber

[VOCALITY]

Dear list,

I would like to place an outbound call (E164 format) from a subscriber 
(Xlite softphone) and send this call to a Voip Termination provider.
My configuration is:

subscriber (E164 format) --------> SPCE server --------> Termination 
provider (E164 format)

I've created a "peering server" for the termination provider - without 
any rewrite rules.

The subscriber Xlite is well registered to my SPCE server - but when I 
try to place an outbound call, it fails !

Please, could you help me ?

Best regards
