HI Arlan. Good morning. If your referring to Jabber which uses VCS Control and TMS to provision the client, then what you have currently will not work.
You need TMS and VCS Control for clients to register and be provisioned for calling services etc. You can of course integrate the ISDN Gateway and MCU if you wish, but its important to know that if your deploying Jabber for Telepresense, VCS control and TMS is needed. If TMS isn't available, VCS Expressway Starter Pack for small deployments is a good product as well. Hope this helps.
