If callmanager goes down (but Unity still up) can phones at both local site and remote site now running in SRST mode (not CME) still access Unity? In this scenario, the WAN is still up, but the single call manager has went down.
In essence there would be no CTI integration to Unity from SRST routers. Is it possible to simply send the DTMF tones to Unity via appropriate dial-peers ?
Or for this type of scenario to happen do we need to run CME for SRST and complete a CME to Unity integration?
thanks in advance,
