What is the firmware version of DX650? So BFCP sharing between DX650 and Jabber Windows works fine in the corporate WiFi but not over Expressway, correct?
Firmware version of DX650 is sipdx650.10-2-4-46.
Yes, BFCP sharing between DX650 and Jabber Windows works fine in the corporate WiFi but not over Expressway.
Per the Release Notes of DX 650 (firmware version 10.2.4),using DX 650 over MRA in production network is not recommended.This version has basic features that can be tested over MRA but looks like it does not have all of those yet.And i won't be surprised if the issue with screen-sharing is stemming from the fact above.
The marketing beta release of Mobile and Remote Access Through Expressway is made available to allow customers to test and evaluate the feature, but is NOT recommended for production use. There is no official Cisco TAC support until the feature is officially released in a future firmware load. To provide feedback, send an email to email@example.com.
Hope this helps.
Let me make it more clear for you.
The issue is: Jabber client [MRA] calls and shares screen with Dx650/80[On_Prem]; DX endpoint does not display the shared content.
Note: Dx650 is not registered over expressway, it is placed on premise only.
