Dear all!

I am new to FreeSwitch and I am trying to map a number for example 654321 to sip adress like this 1005@10.1.1.1 with configuring a local DNS server. When I write enum 654321 in fs_cli it gives me: 

Offered Routes:
Order    Pref    Service       Route
==============================================================================
10    100    E2U+sip       sofia/${use_profile}/1005@10.1.1.1

and seems to be fine.
But when I make a call from my soft phone, the FreeSwitch ends up my call and it gives me error 503 service unavailable.
I have no idea what the problem is, can you please help me?

Thank you in advance
