mediant 1000 fxs 404 error

[mckey415]

Hi all!

We're configuring Audiocodes Mediant 1000 gateway to work with 3CX. Our Mediant has E1 and FXS modules. E1 will be available later and now i'm trying to configure FXS modules for intergration of 3CX and my Panasonic PBX. I managed to get Mediant FXS ports registering in 3CX but when i try to make a call to any extension assigned to FXS ports i get 404 error:

[CM503003]: Call(40): Call to sip:0001@mediant_ip_address has failed; Cause: 404 Not Found; from IP:mediant_ip_address:5060

I suppose that it's something wrong with Mediant config, so i'm posting a mediant log of call attempt (maybe here's some guys who knows mediant systems well enough):
