Numbers hackers call
I see a lot of attempts by hackers to call 00972595301123? or 011972595115207? or variations but that same 972595 is often present.
Can someone break down that dial string with an explanation? The 011 look like an overseas call (from Americas), while the 972595XXXXXX is unclear...

Intro to DECT vs IP
We've deoplyed a number of pure VoIP wireless (wifi & proprietary) phones, but not dect.
Is there a simple overview of integrating DECT phones with Asterisk somewhere? I assume the DECT basestation has a multi-account SIP VoIP interface, and the handsets are just plain old dect?
Can you push configuration info to individual phones? (Are they individually addressible / configurable

Branch based on call volume
Is there a simple way to get call volume from a particular trunk within the dialplan (for conditional branching)?
I suspect we will have to build an AGI script but I'm hoping something new in Asterisk 13

What linux distro most popular for Asterisk
Is there a recent survey of that Linux distro and version people are using for the Asterisk installations? I recall seeing a pie chart over a year ago (I think on a wiki but I can't find it again)....also hoping for something more current.
I suspect RH5 and RH6 are most popular...but I'm looking for facts

Interesting attack tonight & fail2ban them
I happened to be in the cli tonight as some (208.122.57.58) initiated a simple attack - just trying to make long distance calls from outside context. Although harmless, this went on for several minutes as the idiot just used up my bandwidth with SIP messages. Here's and example:

Dual Atom mobo - call capacity
I'm looking for a small formfactor mobo for an install that needs to handle 25 phone sets (no transcoding). I found a new dual atom 1.66GHz mobo - anyone know what kinds of call volume that will handle?

Determine channels in use from CLI
Is the a CLI command that shows all channels in use at one time? (Whether IAX, SIP, SCCP, etc)?
As well, when I "SIP SHOW CHANNELS" I see phones registering showing as channels in use. Is there a way to filter this output?
Thanks!

Disable peer from AMI
I need to disable/enable a peer after hours automatically, and am thinking about doing so via the AMI.
Is there a command to enable/disable (or perhaps delete/add) a peer via the AMI? I could create code to modify sip.conf and force a reload, but that seems like the wrong approach...

Branch based on call volume
?I meant how many calls are in progress on a particular trunk. (Sorry - I didn't even think of the other interpretation).

Can't restart asterisk from script
I'm running * 1.4 and can successfully restart asterisk from the command
line with:
/usr/sbin/asterisk -r -x "restart gracefully"
However, I have a cron job that tries to restart asterisk and gets this
error:
No such command 'restart gracefully' (type 'help restart gracefully' for
other possible commands)
Can anyone think of why this is happening?
Thanks

Occasional robotic sound while call in progress
We have an application that plays a variety of sound files on one leg of a call (generated by a call file). We've been told that the party listening to the audio files intermittantly hears "robotic" sounding audio (on/off during the same call).
Anyone have ideas on cause? These calls are on an internal network (lots of network bandwidth), and from a server running 99% idle.

When are /proc/dahdi files created
Can someone tell me when the /proc/dahdi files are created for spans? Are they created when asterisk starts (or the asterisk init script) - if not what script creates them?

RE: faxing to/from asterisk - new scripts
Roman:
I created two bash scripts called Mail2Fax and Fax2Mail for use with the
asterisk sever.
They leverage the app_txfax and app_rxfax scripts, along with ast_fax. They
make using these apps a lot easier, including being able to mail to
fax@domain.ca for outgoing faxes and then extracting phone numbers from the
subject line! (Makes it easy to use with Sendmail without complex rules /

SSL/TLS weakness impact on Asterisk authentication
After reading about the 2 major SSL (and TLS?) weaknesses discovered this year, I was wondering how it affects asterisk.
Does the SIP authentication use TLS - or something that was recently broken? Is there a risk of exposing passwords?
Thanks!

Best wifi IP phone for asterisk
We're looking at a large wifi phone deployment, and we're looking for wifi
phones that:
1. Are SIP compliant (Asterisk friendly)
2. Provision capable (ideally TFTP of own MAC address)
3. Industrial quality (no cheap plastic stuff).
4. Well documented (and none of the "only telco's get documentation" crap)
Does anyone have a suggestion?
Thanks,

directrtp with SIP + H.323
We're creating a SIP gateway for a client that will take one leg of a call
in via SIP, and out the other side via H.323. To minimize load on the
gateway, we would like to have the RTP stream bypass the gatewayy altogether
(directrtp/reinvite). Is this possible with these to protocols?
Thanks

Audio problems on cable modem link
We have a small office installation running over a cable modem. (8M down, 500k up confirmed with numerous speed test sites)
When a single call is up, call quality is fine. When a second call is up, outbound audio is immediately choppy. We're using ulaw, and confirmed that traffic with 2 calls is <175kbps in/out. (IAX connection out)
Asterisk doesn't report any dropped frames, the

Need T1 crossover cable?
I'm connecting a T1 PCI card to a Nortel Option 61 switch T1 card. My
Sangoma A102D shipped with 2 T1 cables - which I assume are straight
through. Do I need to make crossover cables for this scenario?

app_hackblock to prevent SIP/IAX reg trolling
Has anyone written an app that monitors SIP/IAX registration attempts? A
couple of clients are being flooded with SIP registrations (but the source
IP changes every few hours so IPtables won't do)..
I would think that any attempt to reg 5 times with a bad password should
cause a 5 minute timeout until reg is considered again. Has anyone written
such an app? The name app_hackblock is my
