Vitalii,

You said you want to call both numbers via external provider.
So you want the media to flow from external provider to external  
provider, not from SIP phone to SIP phone.
This should work, but I must admit I never did that with 2 outbound  
legs.
If it doesn't, I would recommend you pastebin the conf and the trace  
of a call attempt.
