Calling Zulu desktop from Zulu Mobile results in 500 Internal Server Error

Very excited about Zulu mobile, trying it out and running into the follwing problem:

When I call a Zulu desktop client (windows) from a Zulu mobile client (Android), the called party rings, but as soon as it picks up, the call hangs up.
Calling the other direction from desktop client to mobile works fine.

FreePBX 15, all upgraded to the latest.

Looking at SIP debug, I see that when the called party picks up, 200 OK messages are exchanged followed by another INVITE, then by a 500 Internal Server Error and a BYE.
