None of those models support MRA, the 7942 supports phone VPN, but not the 7940.

Your best option would be a VPN from the remote site to CUCM so both models can work.

You can uses below Three Options

1) User MRA :- This option will need you to add Expressway-C/E VMs , A dedicated Public IP and Public CA Signed Certficates.
Refer Below document. Phone modle 7900 are NOT Supported . You need 7800 & 8800 Models

2) User Phone VPN :- Here IP Phone need to register internally first and downlaod VPN Configuration from CUCM. You would need ASA Firewall for this. Cisco VPN Phone is supported on 7942G, 7945G, 7962G, 7965G, 7975G, and 99xx series as well as 89xx series.

3) Build a Dedicated VPN and Register phone over normally over VPN.

As suggested by Jaime for you phone models Option 3 will fit.
