Configuring the HTTP Server Allow List on VCS Control
Jabber client endpoints may need to access additional web services inside the enterprise. This requires an allow list
of servers to be configured to which the VCS will grant access for HTTP traffic originating from outside the enterprise.
of servers to be configured to which the VCS will grant access for HTTP traffic originating from outside the enterprise.
Here are some examples of features and services that you may need to add to the allow list:
■
Visual Voicemail
■
Jabber Update Server
■
Custom HTML tabs / icons
■
Directory Photo Host
■
Advanced File Transfer (AFT)
■
Problem Report Tool server
Note:
In order for the AFT feature to work across VCS you must ensure that all Unified CM IM and Presence Service
nodes, across all Unified CM IM and Presence Service clusters, have been added to the allow list either manually or
automatically.
automatically.
To configure the set of addresses to which HTTP access will be allowed:
1.
On VCS Control, go to Configuration > Unified Communications > Configuration.
2.
Click HTTP server allow list.
3.
Configure the hostnames or IP addresses of any HTTP servers that external Jabber clients are allowed to
access.

Access is granted if the server portion of the client-supplied URI matches one of the names entered here, or if
it resolves via DNS lookup to a specified IP address.

VCS Control automatically adds the addresses of all discovered Unified CM nodes (that are running the CallManager
and TFTP service), IM and Presence Service nodes, and Cisco Unity Connection nodes to the allow list. These entries
cannot be deleted. These entries are displayed in the Auto-configured allow list section of the HTTP server allow
list page.

Setting Up the VCS Expressway
This section describes the configuration steps required on the VCS Expressway.
Configuring DNS and NTP Settings
Check and configure the basic system settings on VCS:
1.
Ensure that System host name and Domain name are specified (System > DNS).
2.
Ensure that public DNS servers are specified (System > DNS).
3.
Ensure that all VCS systems are synchronized to a reliable NTP service (System > Time). Use an
Authentication method in accordance with your local policy.
