9. 7. 8 Record malicious calls (MCID)
By activating the Malicious Call Identification service, MCID for short, a user B can
have the threatening or nuisance calls from an external user A recorded by the network
provider so that the caller can be identified. The recording can be activated either dur-
ing the call or after the call during the busy tone signalling (once the caller has rung
off).

Detailed Description
This function provided by the network provider as a supplementary service is used for
identifying malicious or nuisance callers. The identification is effected by the network
provider. The feature is activated by the user.
Suppressing the outgoing number (CLIR) does not protect the caller from identification
of his user number by the network provider.
The following data is recorded by the network provider:
• Calling party’s phone number
• Called party's phone number
• Date and time of the call
