Cisco IP Phone local directory doesn’t load over IPSec

Hi All,

We recently installed a few Cisco 7975 IP phones in one of our remote offices. The setup has one Mikrotik router as gateway and IPSec endpoint. We have a CUCME router in our main office and phones in remote office connect to it through IPSec tunnel. Voice communication works fine between main and remote office but we have one problem.

The local directory doesn’t show up in remote office phones with the error “file not found”. I checked the address http://<CUCME IP>/localdirectory is accessible from same VLAN in remote office. I also checked with 7942 but it remains in “requesting” mode when pressing the Directory button.
