DNS Requirements
The DNS requirements for service discovery through remote access are:
-
Configure a _collab-edge DNS SRV record on an external DNS server.
-
Configure a _cisco-uds DNS SRV record on the internal name server.
-
Optionally, for a hybrid cloud-based deployment with different domains for the IM and Presence server and the voice server, configure the Voice Services Domain to locate the DNS server with the _collab-edge record.
![]() Note |
Jabber attempts connections to a maximum of three SSO-enabled servers, which are chosen randomly from all SSO-enabled servers that the DNS SRV records (_collab-edge and _cisco-uds) identify. If Jabber fails to connect three times, it considers Edge SSO unsupported. |
Certificate Requirements
Before you configure remote access, download the Cisco VCS Expressway and Cisco Expressway-E Server certificate. The Server certificate is used for both HTTP and XMPP.
For more information on configuring Cisco VCS Expressway certificate, see Configuring Certificates on Cisco VCS Expressway.
