I have an SRG50 at a field office thats connected to a CS1000M at HQ. At the SRG50 location a PRI is utilized for all DID and outbound calls. SIP is used for voicemail access and internal calls. Can I set up the employees at the SRG50 location onto AACC to monitor their activity? What would be involved in doing this? Would they loose their survivability?
