So... if I understand this correctly, you're having problems with diverted calls FROM
the Asterisk IVR not being able to authenticate on SER?
Could you just add the Asterisk server to the trust tables and skip the auth process for
calls coming back or would that create problems?

Hi to all!
I've a big problem with SER & Asterisk
I've a network where i put them working together.
Asterisk is the media gateway with PSTN as well as being the serverwhich is making all
the services available (IVR, voicemail, conferencecalls, etc).
SER just routes calls either to the softphones, VoIP phones or to Asterisk who will just
forward the calls to PSTN (via Asterisk).
Till now everything works well except the service IVR which is working on Asterisk.
Details:
MailScanner warning: numerical links are often malicious: 192.168.226.13 - IP SER
MailScanner warning: numerical links are often malicious: 192.168.226.45 - IP Asterisk
The problem is only after the user (roberto(a)192.168.226.13 - authenticated and authorized
in RADIUS) calls IVR.
Till then the user calls, IVR gives some information to the user and everything goes
well.
Problem is when he presses a number which will have to redirect the call to another
user.
And why is there a problem.
Because the initially roberto(a)192.168.226.13 to be able to call IVR had to rewrite host
& port MailScanner warning: numerical links are often malicious: 192.168.226.45 so
that the call would reach Asterisk who would then call to the IVR.
That rewriting turned roberto(a)192.168.226.13 into roberto(a)192.168.226.45. That is, I can
say, that it became a "new user".
While it's on the IVR there's no problem, but when call is diverted it has to
give its credentials...
Credentials that don't exist in RADIUS cause it only accepts usernames that end in
@MailScanner warning: numerical links are often malicious: 192.168.226.13 (IP of SER)
Here is the following code, both of extensions file in Asterisk and configure file of
SER
I hope somebody knows how to solve it or at least find a way how to.
extensions.conf - Asterisk
[sip]exten => 74001,1,Answerexten => 74001,2,SetMusicOnHold(default)exten =>
74001,3,Set(TIMEOUT(digit)=5)exten => 74001,4,Set(TIMEOUT(response)=10)exten =>
74001,5,Background(menu)
exten => 1,1,Dial(SIP/roberto@192.168.226.13:5060,,r)...exten =>
7,1,Goto(sip,74001,1)exten => 8,1,Hangup
ser.cfg - SER
...
if ((uri=~"^sip:7[0-9]{4}@.*")) {
route(5);
break;
};...
route[5] { # Redirecting to Asterisk
# MsgLog
xlog("L_ALERT","(WARNING) Sending to Asterisk request of %fu to
%tu\n");
rewritehostport("MailScanner warning: numerical links are often malicious:
192.168.226.45:5060");
route(1);
}
Thanks for your help,
