Which jabber-config.xml variable do you use to allow remote Jabber users to connect using Collaboration Edge?

`<CollaborationEdge>` is not a valid or recognized parameter in the jabber-config.xml schema for enabling remote access.

The `<RemoteAccess>ON</RemoteAccess>` parameter in jabber-config.xml instructs the Jabber client to initiate a Collaboration Edge discovery process when it cannot reach internal CUCM services directly. This parameter is provisioned via CUCM and is the standard, documented way to enable Mobile and Remote Access (MRA) through Expressway for Jabber clients.

`<RemoteJabber>` does not exist as a configuration parameter in the Cisco Jabber jabber-config.xml parameter reference.

`<Expressway>` is not a defined jabber-config.xml element and has no effect on enabling Collaboration Edge connectivity.

`<AnyconnectVPN>` controls whether Jabber uses Cisco AnyConnect VPN for remote access, which is a separate and mutually exclusive mechanism from Collaboration Edge.
