Caching in OTRS allows you to reuse objects that have been used recently. By default, OTRS has a disk cache. However, this could not be enough if you are planning to do a cluster or you just want to speed things up. Fortunately for us, someone coded the Memcached support. So I will talk about how I did this.
In my very specific case, the VPS where I have installed my OTRS is very slow on I/O operations, so putting a Memcached configuration helped a lot!

Since I have been doing VoIP for a long time now, I think it is a good idea starting to write my experience about using some IP phones. When I talk to people, I always refer myself to this phone as my "trusty SNOM"; in the 4 years I have had it, I can say it has not failed me a single time. With this said, I will talk more about my experience, you can find the tech spec by googling it.
This is the phone I have on my desk for daily use.
First the bad news, this phone has been out of the market for about 3 years. If you want to get one, you will need to get from eBay, Amazon but you will not get it from SNOM directly.
This is the second SNOM phone I have been using for more than a year. I can not tell I am a fan of it but at home, people like it very much. Again, as my previews review of the SNOM 870, I will not talk about technical specs. I will try to talk about some details you will not find by reading about it on the vendor website. This phone has been discontinued, but you can find it on eBay for about 125 USD with the base or 100 USD only the headset.
The model M9 is a wireless (aka cordless) IP Phone. The phone consists of a base that controls up to two headsets and nine SIP accounts. The signal reach of the base is good, I have tried in a three-level house without issues. This phone has a repeater mode, this means that if you have a really big house, you could put two bases and the headset will jump between them.
