SIP Gateway
Please provide a brief overview of what the purpose of a SIP gateway is, and how it can be used.
Yes that's pretty brief! What I want to understand is - I presume it's bidirectional? It also routes voice back to a SIP server. And the phone it connects to - what sort of phone can be used?

A SIP gateway accepts SIP traffic and routes it to phones.

Media Server is a Computer Appliance
A media server is a computer appliance, ranging from an enterprise class machine providing video on demand, to, more commonly, a small home computer, or NAS (Network Attached Storage), dedicated for storing various digital media (meaning digital videos/movies, audio/music, and picture files).

Purpose
By definition a media server is a device that simply stores and shares media. This definition is vague, and can allow several different devices to be called Media Servers. It may be a simple Network-attached storage, a media center PC running Windows XP Media Center Edition, MediaPortal or MythTV, or a commercial web server that hosts media for a large web site. In a home setting, a media server acts as an aggregator of information: video, audio, photos, books, etc. These different types of media (whether they originated on DVD, CD, digital camera, or in physical form) are stored on the media server's hard drive. Access to these is then available from a central location. It may also be used to run special applications that allow the user(s) to access the media from a remote location via the internet.
Hardware
The only requirement for a media server is a method of storing media and a network connection with enough speed to allow access to that media. Depending on the uses and applications that it runs, a media server may require large amounts of RAM, or a powerful, multicore CPU. A RAID may be used to create a large amount of storage, though it is generally not necessary in a home media server to use a RAID that gives a performance increase because current home network transfer speeds are slower than that of most current hard drives. However, a redundant RAID configuration may be used to prevent accidental loss of the media files. Many Media servers also have the ability to capture the media. This is done with specialized hardware such as TV tuner cards. Analog TV tuner cards can capture video from analog broadcast TV and output from cable/satellite set top boxes. This analog video then needs to be encoded in digital format to be stored on the Media server. This encoding can be done with software running on the Media server computer or by hardware on the TV tuner card. Digital TV tuner cards take input from broadcast digital TV. In the USA, the ATSC standard is used. In most of the rest of the world, DVB-T is the accepted standard. Since these transmissions are already digital, they do not need to be encoded.

Media Servers in Performance Environments
The growing use of motion graphics in environments such as Theatre, Dance, Corporate Events and rock tours has led to the development of media servers designed specifically for live events. These machines are often high-spec home computers with increased RAM or hard drive technologies such as RAID arrays or Solid State Disks. They are then supplied with software which allows the control and manipulation of video content, much like VJ software. One of the primary functions of these machines is to allow current show control technologies to control the playback of video content. Thus, a media server system may include inputs for DMX, MIDI or similar control protocols.
Media Servers in Telephony
In the world of telephony, a media server is the name given to the computing component that processes the audio and/or video streams associated with telephone calls or connections. Conference services are a particular example of how media servers can be used, as a special 'engine' is needed to mix audio streams together so that conference participants can hear all of the other participants. Conferencing servers may also need other specialized functions like "loudest talker" detection, or transcoding of audio streams, and also interpreting DTMF tones used to navigate menus. For video processing, it may be needed to change video streams, for example transcode from one video codec to another or rescale (transrate) a picture from one size to another. This media processing functions are the core responsibility of a media server.
With telephony networks moving more towards VoIP technology, and using Session Initiation Protocol (SIP), the idea of media servers has started to gain some traction. Typically, an application (the 'application server') has the controlling logic, and controls a remote media server (or multiple servers) over an IP connection, possibly using SIP. Protocols such as Netann, MSCML and MSML have been created for this way of working, and a new protocol, MediaCTRL is under development at the IETF.
The IP Multimedia Subsystem (IMS), the blueprint for next generation networks, defines a component called the MRF (Media Resource Function), which is a kind of media server. In the case of IMS, the 'controlling logic' is provided by the MRFC (MRF controller), which, along with layers above constitutes an 'application server'. Although the MRF has been associated largely with the legacy telecom H.248 protocol (see Gateway Control Protocol), it is likely that SIP-based protocols like MediaCTRL will ultimately prevail.

Media Server - Definition
Media Server - Definition
A Media Server, is a network element, deployed in Enterprise and Service Provider voice networks, which supplies media related functions such as media manipulation (e.g. voice stream mixing) and playing of tones and announcements.
Under the IMS (IP Multimedia Subsystem) definitions, a Media Server is defined as an MRF (Media Resource Function). Each MRF is further divided into a Media Resource Function Controller (MRFC) and a Media Resource Function Processor (MRFP). The MRFC is a signalling plane node that acts as a SIP User Agent to the S-CSCF, and which controls the MRFP with a H.248 interface. The MRFP is a media plane node that implements all media-related functions.

Cara-cara Anda Baru
Kumpulan Tips Motivasi Mario Teguh
October 10th, 2008 •
Anda pasti kenal dengan Mario Teguh sang Inspirator yang wajahnya sering menghiasi salah satu TV swasta di Jakarta, dan juga seorang bergerak di bidang Bussiness Efectiveness Consultant. Selain wajahnya yang teduh sekaligus pembawaannya dalam menyampaikan yang khas. Tentu yang takkan pernah terlupakan adalah tips dan motivasinya. Berikut ini adalah Tips Motivasi dari Mario Teguh mudah-mudahan menjadi pemompa semangat bagi kita yang ingin maju.
Jika anda sedang benar, jangan terlalu berani dan
bila anda sedang takut, jangan terlalu takut.
Karena keseimbangan sikap adalah penentu
ketepatan perjalanan kesuksesan anda
Tugas kita bukanlah untuk berhasil. Tugas kita
adalah untuk mencoba, karena didalam mencoba
itulah kita menemukan dan belajar membangun
kesempatan untuk berhasil
Anda hanya dekat dengan mereka yang anda
sukai. Dan seringkali anda menghindari orang
yang tidak tidak anda sukai, padahal dari dialah
Anda akan mengenal sudut pandang yang baru
Orang-orang yang berhenti belajar akan menjadi
pemilik masa lalu. Orang-orang yang masih terus
belajar, akan menjadi pemilik masa depan
Tinggalkanlah kesenangan yang menghalangi
pencapaian kecemerlangan hidup yang di
idamkan. Dan berhati-hatilah, karena beberapa
kesenangan adalah cara gembira menuju
kegagalan
Jangan menolak perubahan hanya karena anda
takut kehilangan yang telah dimiliki, karena
dengannya anda merendahkan nilai yang bisa
anda capai melalui perubahan itu
Anda tidak akan berhasil menjadi pribadi baru bila
anda berkeras untuk mempertahankan cara-cara
lama anda. Anda akan disebut baru, hanya bila
cara-cara anda baru
Ketepatan sikap adalah dasar semua ketepatan.
Tidak ada penghalang keberhasilan bila sikap
anda tepat, dan tidak ada yang bisa menolong
bila sikap anda salah
Orang lanjut usia yang berorientasi pada
kesempatan adalah orang muda yang tidak
pernah menua ; tetapi pemuda yang berorientasi
pada keamanan, telah menua sejak muda
Hanya orang takut yang bisa berani, karena
keberanian adalah melakukan sesuatu yang
ditakutinya. Maka, bila merasa takut, anda akan
punya kesempatan untuk bersikap berani
Kekuatan terbesar yang mampu mengalahkan
stress adalah kemampuan memilih pikiran yang
tepat. Anda akan menjadi lebih damai bila yang
anda pikirkan adalah jalan keluar masalah.
Jangan pernah merobohkan pagar tanpa mengetahui
mengapa didirikan. Jangan pernah mengabaikan
tuntunan kebaikan tanpa mengetahui keburukan
yang kemudian anda dapat
Seseorang yang menolak memperbarui cara-cara
kerjanya yang tidak lagi menghasilkan, berlaku
seperti orang yang terus memeras jerami untuk
mendapatkan santan

Memindahkan Website Joomla Satu Server ke Server Lainnya
Memindahkan Website Joomla Satu Server ke Server Lainnya
January 20th, 2009 • Related • Filed Under
Filed Under: Joomla
Tags: Joomla
Jika Anda telah membuat website joomla di server lokal dan ingin di publish ke server web hosting kita, namun kita tidak ingin kehilangan settingan sebelumnya. Atau Anda ingin sekedar memindahkan web kita dari satu server ke serverlainnya maka beberapa hal yang musti anda lakukan adalah sebagai berikut. (Contoh ini adalah menggunakan Joomla versi 1.0.xx) jika anda menggunakan versi 1.5.xx pada prinsipnya sama yang perlu di edit adalah file configuration.php.
1. 1. Copy seluruh file Joomla dan database Joomla Anda ke server baru. Ada baiknya seluruh file di server lama di kompress ke dalam 1 buah file zip, kemudian copy file zip tersebut ke server baru. Selanjutnya unzip file zip tadi menggunakan program puTTy (Linux only) atau menggunakan fasilitas extraxt pada cPanel hosting anda. Jika dalam komputer lokal anda cukup Unzip saja.
2. 2. Kemudian di server baru tersebut, buka file configuration.php, kemudian pastikan parameter-parameter berikut ini sesuai dengan kondisi di server yang baru.
$mosConfig_absolute_path: “lokasi/file/joomla”;
$mosConfig_cachepath: “lokasi/cache/joomla/cache”;
$mosConfig_db: “nama_database”;
$mosConfig_live_site: “http://urlwebsitejoomla”;
$mosConfig_password: “password_database_joomla”;
$mosConfig_user: “username_database_joomla”;
Jangan lupa import database dari server ke server menggunakan PHPMyAdmin
Catatan : Jika file configuration.php tidak bisa di write, chmod dahulu file tersebut ke 755, jika proses perubahan parameter sudah selesai jangan lupa untuk chmod lagi ke 644. (Dan jika di komputer (lokal) maka seharusnya Webhosting Anda sudah bisa berjalan)
Oke selamat mencoba, mudah-mudahan Anda sudah bisa memindahkan website Joomla anda dari satu server ke server lainnya.
