Description

The Asterisk project reports:

If Asterisk is challenged on an outbound INVITE and

the nonce is changed in each response, Asterisk will

continually send INVITEs in a loop. This causes Asterisk

to consume more and more memory since the transaction

will never terminate (even if the call is hung up),

ultimately leading to a restart or shutdown of Asterisk.

Outbound authentication must be configured on the endpoint

for this to occur.
