Invoke custom destination via incoming trunk

I have a custom destination I can invoke by connecting to an extension via a softphone and dialling a feature code. But what I want is to access that custom destination by dialing some extension or feature code on a different pbx (actually a Grandstream UCM 6102 that I administer), connecting the 2 PBXs with some kind of trunk. Both are behind the same firewall, so NAT and firewall rules are not an issue. I have tried many types of peer and auth trunks, both IAX and SIP. But cannot get any call out of the UCM to the FreePBX custom destination. Has anybody ever made something like this worked?

Without more information, I’m going to guess it’s a context issue. Lots of things that work “from-local” do not work “from-trunk”.
