Hi.


I have 3 sites (1 central and 2 remotes).

In each site I have a cluster with 2 CCM and a router to PSTN only.

Don't have SRST in remotes sites.

Have any solution to the phones of remotes site registers in central site and only the central site down the cluster local(remotes site) manager the calls?


Thanks

You can set up a VPN (or purchase a dedicated point-to-point link) and link your CallMans together.


Set the remote sites up as subscribers and one of the CCMs in your central site as the Publisher. In the device pool for the phones, then you just specify the desired CallManager to register with as the CallManager in your central site (the subscriber in your central site preferably), and a secondary CallManager in the local site. You may want to specify a third CallManager for your phones to fall back to if necessary.


With that said, keep in mind that if your remote link goes down, the phones would re-register with the local CallManager, then when they detected the remote CallManager was up, they'll re-register with the remote server and could swamp your link.
