asterisk users - Apr 2004 - no signal, mgcp

Hi,

I'm trying to connect asterisk on FreeBSD and mtas.
I have registered endpoints, but after I pick up the receiver I hear
nothing, there is no signal.
There is a message:

-- MGCP mgcp_new( endpoint ) created in state : Down

I'm concerned about messages like
chan_mgcp.c:372 __mgcp_xmit: mgcp_xmit returned -1: Address family not
supported by protocol family

Can asterisk work without soundcard.?
Can anyone help ?

Thanks
