About Call-Shadow

Call-Shadow is an easy to use call recording solution that implements the corporate call record keeping policy and provides secure, easy access to call records.

It allows managers to review phone calls according to their workgroup.
Users are empowered by providing them with accurate records of their calls.

Call-Shadow can be used in mission critical implementations, because it has a clustering system with an advanced fail-over system, with no single point of failure. Should a server in a cluster become unavailable, its workload is divided between its peers without operator intervention. Such a clustering system is much superior to a simple hot-swap standby system because all servers are working, providing scalability and redundancy at the same time.

All access to replays is logged and can be audited by authorized users.

Call-Shadow is highly integrated with Cisco CallManager, having an XML phone service which allows replaying calls directly on the phone, and being integrated with CallManager’s user directory (LDAP DCDirectory) for unified authentication.

It is available in two configurations, to facilitate application in a call center or company-wide.

Features and Benefits

  • Record phone calls according to flexible policies. You can record every call and keep only what  is important. Rules and filters can be defined to organize calls by phone number or user name patterns.
  • Monitor live calls: Listen to a call as it happens, without any conferencing. You can also whisper to the agent without being heard by the external party.
  • Review, Adnotate and e-Mail phone call recordings. Search by caller ids, phone numbers, adnotations, time. Everybody can access their own calls by default, but only designated supervisors can access other phone calls.
  • Organize calls using flexible, color coded, folders. Calls can also be automatically assigned to folders, using filters.
  • Call Retention Policies - Recordings can be kept for a period of time or until the hard-drive is filled. Some calls are more important than others, so rules can be set to manage each category differently.
  • On Demand Recording lets you keep just the important calls, using a phone service.
  • Multi Site: With Call-Shadow, you can record and administer many network partitions as if they were one, at no additional cost.
  • Mission Critical Reliability – peer to peer clustering system with no single point of failure. Should a server failure occur, its peers in the cluster will automatically detect it and share the workload. Calls in progress are recorded from where it left.
  • Scalable to thousands of ports, when using multiple servers. Calls can still be browsed & searched from a central server. The actual recordings storage is distributed amongst servers.
  • Specialized Speech Compression lowers the storage requirements 8 times over MP3 and allows 18,000 hours of phone calls storage on one 120 GB hard drive.
  • Call History - follow a call as it is transferred, put on hold or parked
  • Audit Replays – prevent recordings abuse by browsing the list of accesses to a call.
  • XML Phone Service – handily review your past calls from your XML enabled phone (Cisco IP Phones 7940, 7960 & 7970). Authenticate, Browse, Play, Rewind, e-mail, mark important. You can also assign calls to folders.

  • Thin Client Deployment – The administration and user tools run in a web browser, be it Internet Explorer, Firefox or Opera.
  • Integrated Authentication - Authentication is integrated with Cisco CallManager's directory server, so user accounts and passwords need to be set only once.
