It looks like I am the most referred person within tobitoon. I don't envy Josha, who had been called all his visit Lothar.

A brand Rimowa Salsa Multiwheel 869.77 (110 liters) suitcase at the beginning of a longer trip.

Ein nagelneuer Rimowa Salsa Multiwheel 869.77 (110 Liter) Koffer vor einer langen Reise.

mit allen seinen Rädern

After each US flight one was missing, therefore the suitcase arrived back home like this. Maybe the US luggage handle staff had this Rimowa wheel cracking challenge. To be fair, the suitcases weight was about 31.5 kg, but the wheels should have handled that anyway.

Nach jeder Teilstrecke fehlte dann ein Rad, und der Koffer kam so wieder zuhause an. Vielleicht gab es ja einen Wettbewerb unter den Gepäckmitarbeitern an den US Fluhäfen "hey, a Rimowa, lets see if the wheel cracks". Der Koffer wog zwar 31.5 kg, aber er hätte das dann doch schadlos überstehen müssen.

Rimowa claimed a manufacturing problem and sent me new wheels (I did not want to bring it back into the shop).
Let's see, if they survive next time.

Rimowa beruft sich auf ein Herstellungsfehler bezüglich der defekten Räder und schickte mir Ersatzräder (da es mir zu mühsam war mit dem Koffermonster in einen Laden zu gehen).
Nun bin ich mal gespannt, ob diese die nächste Reise überstehen.

Yet another tobitoon with reference to me.

Please give tobitoon lots of comments .

It took me 20 years to get into one of the genius comics of my old friend from school Tobi. My visit to Alex & Tobs (plus the kids & the dog) finally made it happen.

Here it is!

fortschreitende Helvetisierung v0.2

intro

This howto is a extension to my recent "simple (fixed) asterisk callback configuration". This configuration is useful to trigger a callback from a location you rarely use, but provides a callerID. This is for example useful in hotel rooms for one night, phone cells, friends homes. The call process is the following:

1. you call from a phone with callerID 004144555111 the trigger number 004144555666
2. wait for the busy signal
3. hangup
4. wait until the phone rings
5. enter password
6. enter target number

The target number will then be called according to the outbound call routing in your pbx.

1. The system recognizes rejects all calls on the trigger number.
2. It uses the callerID and generates a temporary call file which will will be copied from a directory (/var/spool/asterisk/ in the example below) into the outgoing directory
3. asterisk initiates the outbound call according to the rules in the call file
4. once you pick up the callback call, you will get a dialtone and be able to dial as from a local extension

The goal of this small nerd activity is that my slimp3 networked mp3 players display displays the callerID of inbound calls so that I see who is calling even without looking at a phone. I have a networked slimp3 player in my living room as well as in my office.

Update: if you own a dreambox, see this article as well

prerequisites:

• asterisk server
• slimserver
• any kind of slimp3/squeezebox/transporter device from slimdevices
• slimdisplay.pl script (see below, modified based on gwendesigns SlimServer announcement script)

purpose:

Display incoming caller information on your squeezebox.

intro

This a simple howto get a callback feature into asterisk.

Its based on the assumption, that you have a account at a provider, which lets you dial into your box remotely and the location you call from provides a callerID. So this setup is mostly useful, if you have a flatrate at home and would like to use it, lets say, from your parents place.

The call process looks is the following:

1. you call from the phone which sends the caller ID 004144555111 the trigger number 004144555666
2. wait until you get a buisy signal
3. hangup
4. wait until it rings
5. pick it up
6. enter password (optional, see security remark)
7. enter target number

Of course, you can setup more than one of those in case you are in a hotel and your room fone provides direct dial through callerID. Just install it temporarily for your hotel stay on your home asterisk.

Security remark: The authentication of the callback trigger is based on the callerID of the calling line. If your SIP provider allows SIP URI calls the callerID might be spoofed. I thats the case, you should but additional security in place (like a password, see below).

A more complicated setup which allows to trigger a callback from any number can be found here.

how does it work

1. The system recognizes the number you dialed and the number you dialed from (CallerID)
2. the call gets rejected
3. a fixed call file will be copied from a directory (/var/spool/asterisk/ in the example below) into the outgoing directory
4. asterisk initiates the outbound call according to the rules in the call file
5. once you pick up the callback call, you will get a dialtone and be able to dial as from a local extension

Adam brought his frustration about Apple Displays to the next step by providing a video:

and made me aware of it in his comment in my blog

I wrote about that twice here:
