Hi David,
This appears to be a new error log in Asterisk 1.8, and the Adaptive Ban plugin
does not yet catch it.
The Asterisk code is:
--
ast_log(LOG_NOTICE, "Call from '%s' (%s) to extension"
" '%s' rejected because extension not found in context '%s'.\n",
S_OR(p->username, p->peername), ast_sockaddr_stringify(&p->recv),
decoded_exten, p->context);
--
So we should be able to easily add this to the Adaptive Ban plugin.
Wouldn't it be nice if all of Asterisk's serious error logs had a common
format, containing the source IP address.
