Inbound calling not working in SRST mode

[Conleyjo]

In SRST mode, everything works except for inbound calls. The IP phone is registered and able to make outbound calls to the POTS network and to other IP phones in SRST mode. When a incoming call is made, the inbound CO port comes off hook. Somewhere I have a problem between the FXO port and the IP Phone. Do I need Dial-peer statements for SRST mode? The router is running MGCP, and is using H.323 in fallback mode. I have the default-destination line, and the router cannot find the phone. I want all inbound calls from the CO line to go to extension 4690.

Here is the config. What am I missing?

call-manager-fallback
limit-dn 7910 2
limit-dn 7940 2
limit-dn 7960 2
ip source-address XX.XX.XX.XX port 2000
max-ephones 24
max-dn 12
default-destination 4690
access-code fxo 9
voicemail 915121111111
call-forward busy 915121111111
call-forward noan 915121111111 timeout 20
time-format 24
date-format dd-mm-yy

Thanks
