In a world where digital communication powers global business, SIP (Session Initiation Protocol) has become the backbone of voice connectivity. However, as voice over IP (VoIP) grows, so do the threats. Without robust security, SIP lines are vulnerable to attacks, fraud, and call manipulation. That’s where Opentact steps in—not just as a SIP provider, but as a security-first telecom solution.
What Makes SIP Connections Vulnerable?
Traditional SIP connections can be susceptible to:
Unauthorized access or SIP account hijacking
SIP trunk spoofing
Eavesdropping and interception of call data
SIP flooding and DoS attacks
Toll fraud
These threats can severely impact operational security and lead to financial and reputational damage.
