Service Discovery Requirements
Service discovery enables clients to automatically detect and locate services on your enterprise network. Expressway for Mobile and Remote Access allows you to access the services on your enterprise network. You should meet the following requirements to enable the clients to connect through Expressway for Mobile and Remote Access and discover services:
Test external SRV _collab-edge.
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.
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.
Test _collab-edge SRV Record
Test SRV Records
After creating your SRV records test to see if they are accessible.
You can also use the SRV check tool on the Collaboration Solutions Analyzer site if you prefer a web-based option.
Open a command prompt.
The default DNS server and address is displayed. Confirm that this is the expected DNS server.
Enter set type=SRV.
Enter the name for each of your SRV records.
