Note: In order for the AFT feature to work across Expressway 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
whitelist either manually or automatically.
Presence Service nodes, across all Unified CM IM and Presence Service clusters, have been added to the

To configure the set of addresses to which HTTP access will be allowed:
1. On Expressway-C, 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.

Setting up the Expressway-E
This section describes the configuration steps required on the Expressway-E.
Configuring DNS and NTP settings
Check and configure the basic system settings on Expressway:
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 Expressway systems are synchronized to a reliable NTP service (
System > Time
). Use
an Authentication method in accordance with your local policy.
If you have a cluster of Expressways you must do this for every peer.
Note: The combination of <System host name>.<Domain name> is the FQDN of this Expressway-E.
Ensure that this FQDN is resolvable in public DNS.
Ensure that this FQDN is resolvable in public DNS.
If you have a cluster of Expressway-Es, you must ensure that the Domain name is identical on each peer,
and it is case-sensitive.
and it is case-sensitive.
