Are you using SIP (on the dial peer and CUC ports)? If not, I’d use SIP as it tends to work better in my experience. Additionally, make sure the dial peer’s DTMF method supports RTP-NTE (dtmf-relay rtp-nte). Make sure you have codecs in the dial peer matched for whatever you have set in CUC (G711ulaw should work by way of default settings in CUC).
Also, verify the VGW is specifying a MWI server (mwi-server xx.xx.xx.xx unsolicited).

So I do appreciate if anyone have a working configuration example of such scenario which makes the AA on local CUC works during SRST situation (WAN outage) or at least highlight the needed configurations. Thanks.
