The information in the document created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.
Step 1. Set up an administrator user account with API permission or can use the administrator account for Cisco Unified Communications Manager. Please find how to create a user with API access.
You can create additional user accounts for the MMP that have admin level rights using the MMP
Add user command user add <account name> <role>.
SSH into the MMP.
Add an admin level user account, for example
Step 2. Configure CMS to support dual screen feature using API.
POST, parameter compatibilityProfiles.
POSTMAN API is used but any API tool can be used for configuration.
Step 3. Use GET operation to get the unique id for compatibilityProfiles/<compatibilityProfiles id>.
Step 4. Use PUT operation for sipMultiStream=true.
Step 5. Apply the configured compatibilityprofile under system/profiles. This is applied to the profile at top level and isused as global profile.
This image shows the compatibilityprofile being applied successfully.
The above is the required configuration to setup DualScreen feature on CMS. Now, you need to also configure an ednpoint with required configuration. The endpoint must run CE9.1.3 or later version of software code.
Step 6. MultiStream Mode on an endpoint must be set as AUTO as shown in this image.
Step 7. On Call Manager when configuring Sip trunk please keep in mind the sip profile used must have following parameters.
SDP Transparency Profile Pass all unknown SDP attributes.
Note: When the system is in a three-screen setup, for example the Cisco Telepresence SX80, MX700 or MX800, the third screen is reserved for content while in a dual screen call.
Use this section in order to confirm that your configuration works properly
Consider, SX, MX700/800 to work as a dual screen endpoint. The layout of participants would appear as shown in the image and if you have an additional third monitor connected, the presentation should appear on the third monitor.
Ensure to verify the software version for an endpoint, CUCM & CMS. Once confirmed the versions are supported then further troubleshooting is required
CUCM is unable to recognized parameter like cisco-scr which is required for DualScreen feature to work. As the following endpoint is registered to Call Manager and there is no trunk in between. Checked the "SipProfile" configured for an endpoint analysed and found the setup using Standard Sip Profile rather it should use "Standard SIP Profile For Telepresence Endpoint"
