Inter-Asterisk eXchange Protocol Detection

info Nessus Plugin ID 20834
New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.


The remote system is running a server that speaks the Inter-Asterisk eXchange Protocol.


The Inter-Asterisk eXchange protocol (IAX2) is used by the Asterisk PBX Server and other IP telephony clients/servers to enable voice communication between them.


If possible, filter incoming connections to the port so that it is used by trusted sources only.
