[VOIPSEC] CALEA Enforcement

[Jim Donovan]

Hi Sachin - 

The CALEA requirements you mention in your note are one of the reasons
why Covergence has developed mid-stream encryption / decryption
capabilities as well as extensive call recording capabilities.    The
mid-stream encryption / decryption capabilities allow you to run SIP TLS
and/or SRTP in your network and our appliance will remove the
encryption, capture the bidirectional RTP packets, and if necessary,
re-encrypt for transmission to the next hop in the network.     Our
appliance has dedicated hardware to ensure that the integrity of the
media is not impaired as a result of this process.   The captured RTP
streams are then coupled with an accounting record.    This information
can be stored on our appliance or swept out to third-party database.
The stored media recording and associated call record allows the
captured media to be accessed by law enforcement personnel or network
technicians for the purpose of troubleshooting call quality.   Whether
or not an individual call is recorded is done based on a finely granular
policy that allows the network operator and law enforcement personnel to
determine who, what, and when to record.        

Thanks,
Jim
