Summary

The IAX2 channel driver in Asterisk, when configured to permit unauthenticated calls, is susceptible to a denial of service attack. This occurs when the system sends 'early audio' to an unverified source IP address in response to a spoofed NEW message, allowing remote attackers to leverage this feature for traffic amplification, potentially overwhelming the service and disrupting communication.
