While the companies serving in the sector are creating their infrastructure, they mostly allocate their resources to hardware and software that will provide the sound transport infrastructure due to these high costs.

Reporting

The main task of the mediator server is that the servers produce the call detail records in their own formats, detailing them and in their own order; The fact that every CDR generating system can transmit call detail records to the relevant sub-unit by converting them to the structure they accept. The absence of such a bridge makes it necessary to develop additional software in order to ensure smooth data flow.

Rosa SIP Firewall detects and blocks the anomaly of network traffic by listening to the structure.

Technical Capabilities

SIP Firewall allows the requests by pre-analyzing the incoming requests without registering by proxying or preventing the passing traffic.

SIP ALG Method

When a message packet containing Session Description Protocol (SDP) arrives, ALG allocates the port for this packet and creates the corresponding NAT mapping. Because Session Description Protocol needs cascading ports for Real-Time Transport Protocol (RTP) and Real-Time Control Protocol (RTCP) channels. ALG provides sequential ports for this need. If it is not possible to provide these sequential ports, ALG discards the SIP message.

IP Ban

During voice transmission over UDP Protocols, login authentication is allowed based on destination ip information. However, it analyzes abnormal behavior. Accordingly, the incoming source IP address is banned.

Domain Based Multi-Tenant Access Control

IP-based accesses are added to the direct ban system by waiting for the requests to come with the FQDN address during the internal registration process from the outside world. and dynamic rule is added to Firewall.

Prohibited Obligations

Pursuant to the law numbered 5651, which is stated in the law on keeping the access records of the Telecommunication Communication Presidency, the format of the records obtained in the format requested by the Presidency and compliance with the law imposes a standard and obligation.

Accordingly, IP-based switchboard users, especially voice providers, businesses with at least 10 personnel are indirectly obliged to keep their call records (CDR) and send them to voice providers.
