Sedwards@sedwards.com Causes Me To Be Knocked Off The List

Report
Question

Someone on this list uses the address @sedwards.com

I doubt this is their actual email address as there is no MX record for sedwards.com and I can't find registration for their domain either.

Part of my mail servers reject these emails because they cannot be replied to, or are likely to be spam.

Every so often I get a mail from the list management to say that I've been unsubscribed because of excessive bounces and it takes a single click to re-register.

It's a bit of a niggle for me. What do you think I should do? Change my servers so that I don't…

Results Of Security Honeypot Experiment - Scraping For IP's/credentials ?

Report
Question

The results of a security experiment were published this week, in which an Asterisk PBX was set out in the wild to see who would attack it and how:

http://www.telium.ca/?honeypot1

What I find particularly interesting is that people/bots are scraping support websites looking for valid IP's of PBX's, and valid credentials!

A good reminder to everyone on this list to not publish the IP of their PBX's, or even account names (in postings) as they will be quickly targeted....

Forward Loop Protection...

Question

Ia had a server overload today because someone did a call forward to their own extension. To do a call forward I write a key called CFWD with the extensión number and number to dial . The main script tests if the key/value exists and dials the number stored in the database.

How To Invoke A Binary File From The Dial Plan?

Report
Question

Hi everyone.

I'm new with Asterisk and I have to create a dial plan that will invoke a binary code. That is, asterisk will execute a program in the same machine. How to do it?

Let me explain what I have to do:

When the user executes an application on his/her phone, it will presents a button to unlock a remote gate or door.

Question

Hi list!

I read the pages that Steve sent to the list. It sounds nice, but I didn't found any documentation about available SIP-Header on my phone (ST2022, not ST2030!).

Is there a possibility to ask the phone which header it understand? Or to get this list in other ways?

Thanks a lot Luca Bertoncello (lucabert@lucabert.de)

Signaling Incoming Call

Report
Question

Hi list!

Finally I got my Asterisk works with my two phones... It was a problem on my Firewall (for the phone of my wife) and on my Dialplan (for forwarding calls).

Now all works as expected, at least in the simulation I did with AsteriskNOW. Hopefully it will work later, when Deutsche Telekom changes my ISDN to VoIP...

Well, now I have some time to spend with "fooling"... My phone will receive calls from 3 numbers. All that was done in my dialplan. Now, it would be nice, if I can signaling on the phone which number will be called, so that,…

Looking For Best Practices

Report
Question

I currently run an Asterisk server on a NetBSD system. It mostly works but sometimes I have weird issues. As far as I can tell they are usually NAT issues.

I have a Cisco SPA-2102 with two phone numbers installed. I have NAT Mapping and NAT Keepalive enabled. No STUN server. Both are using 5060. This is behind an ADSL through a WRT54GL with no special port handling.

The server is 11.15.1. My sip.conf includes this:

[general] context=unauthenticated allowguest=yes udpbindaddr=0.0.0.0 nat=force_rport,comedia srvlookup=yes qualify=yes

All of this works fine. It also works fine with the few clients that I have connected. However, certain changes cause…
