exten => _X.,n,Hangup

I call DID numbe ->A2billing->Enter number->trunk = I hear "...enter destination number..." but when connects to trunk then no sound, but client hear my voice.
I call DID numbe ->A2billing->mysoftphone = working fine.
No audio when I call via to phone via trunk and use DID number (ONLY WITH Didlogic provider, codec is G711)
I tested with other did providers and no problems.
I have direct ip (no NAT)
Tested all combinations in sip.conf with NAT.
