NO JOY FreePBX Rest Apps on Aastra 6867i

[hbonath]

I started this over on the FreePBX forum - I hate spraying different forums with the same question, but it's been some time with Zero response over there, and besides, I like you guys way better over here =)

Hello, we recently purchased to REST Apps and have been testing them in an effort to move away from the legacy Aastra XML Scripts for our customers.
We've had some problems with the Voicemail Apps on both the 6737i and new 6867i.
The 6867i works amazingly well, however we have found that there does not seem to be an option to record greetings from the App, I know this was available in the older Aastra XML scripts.
The 6737i App seems to be broken altogether, I can't seem to play any voicemails, and when I launch the app and try to navigate with the arrow keys I end up marking old voicemails unread instead of playing them or viewing them.
Are these known issues or do I have something wrong on my setup: FreePBX Distro 5.211.65-19
Thank you!
