That was the Auto-Attendant (AA) you routed to on sipXecs, not the ACD,
but that's not the problem.

Your gateway sent:
INFO sip:1...@192.168.0.2:5100 SIP/2.0.
Content-Type: application/dtmf-relay.
Content-Length: 23.
Signal=2.
Duration=70.
and sipXecs AA replied:
SIP/2.0 405 Method Not Allowed.
sipXecs does not support DTMF transport via INFO messages. If you can
configure your gateway to send using RFC 2833 telephony signaling in
RTP, it should work.
