Ensuring Reliable Call Service and Mitigating Disruptions
Maintaining reliable call service is essential for uninterrupted communication. This article addresses common concerns about call reliability, including the impact of Fraud Protection and steps to mitigate SIP attacks on desk phones.
Does Fraud Protection Affect Call Reception?

Blocking risky calls
Alerting you to unusual call spending
Monitoring for potential fraud
This feature operates in the background and does not interfere with incoming call reception.
How to Mitigate SIP Attacks on Desk Phones
SIP attacks, such as nuisance calls from spoofed or changing caller IDs, can disrupt your service. If blocking individual numbers is ineffective, you can secure your desk phone by adjusting its settings to trust only your provider and block direct IP calls. Below are general steps for Yealink desk phones:
Find the Phone’s IPv4 Address - On the handset, press OK to view the Status and note the IPv4 address.
Access the Web Interface - On a computer connected to the same network, enter the phone’s IPv4 address in a web browser. - Log in using the phone’s admin credentials.
Adjust Security Settings - Navigate to Features > General Information (or a similar menu). - Enable Accept SIP Trust Server Only. - Disable Allow IP Call.
Save and Apply Changes - Confirm and save the updated settings.
These adjustments help prevent unsolicited SIP traffic and direct IP calls, reducing the likelihood of SIP attack bursts. For other phone models, consult the device manual for similar settings.
