2. What is Asterisk:
The Definition of Asterisk is described as follow:
Asterisk is a complete PBX in software. It runs on Linux, BSD,Windows (emulated) and provides all of the features you would expect from a PBX and more. Asterisk does voice over IP in four protocols, and can interoperate with almost all standards-based telephony equipment using relatively inexpensive hardware. Asterisk provides:
1) Voicemail services with Directory
2) Call Conferencing
3) Interactive Voice Response
4) Call Queuing
5) Three-way calling
6) Caller ID services
7) Support ADSI, IAX, SIP, H.323, MGCP and SCCP/Skinny
Chapter 2 Card Installation and Configuration
1. Hardware Installation and Setup
1) Configure the Jumper Settings
Please refer jumper setting for details. To install B400P, user should follow the steps.
A. Setting Card ID Switch
If user wants to install more than one cards of B400P in one pc, you should take care of the card id switch. It has three rules, which user must follow:
1. The card id of the first card must be set to 0, and the second card should be set to 1, and so on.
2. The First Card is a card that will be initialized (i.e installing driver) first when system is booting.
3. At most of cases, Linux will initialize PCI devices according to PCI slot order. The slot is nearest to the CPU will be initialized first; the slot at the far end from CPU will be initialized at last. That is to say, if user has more than one cards of B400P in pc, the one is nearest to CPU should be set to card id 0.
B. Adjusting Termination of S/T Interface (100 ohm)
1. If a port will work on NT mode, user should set jumper to CONNECT (ON).
2. If a port will work on TE mode, Theoretically it should be to OPEN(OFF), but user might connect to some non-standard isdn terminal equipments that do not have terminal resistors, for such equipments, you should set it to CONNECT(ON).
C. Power Feeding Connector
These jumpers control whether the card will feed power to the external isdn terminal. User should adjust accordingly.
1) If the port will work on TE mode, user MUST set the jumper to OPEN(OFF)
2) If this port will work on NT mode, the ISDN terminal requires ISDN power supply, user should set the jumper to CONNECT(ON). ISDN terminal does not require ISDN power supply, user should set the jumper to OPEN(OFF).
D. Power Feeding Input
If one of the four power feeding connectors is CONNECT(ON), user should connect a D-type connector from pc power supply to this jack, the D-type connector is used to provide power to your CDROM ahd 3.5”HDD.
E. Power Supply
Some newest model PCs do not provide +5V on the PCI slots, at those cases, use has to set the jumper to 3.3v.
F: PCM IN/PCM OUT
This feature will be used to connect two BRI cards.
2) Power off PC, remembering unplug the AC power cable
3) Put B400P into a 3.3v or 5.0v PCI slot
4) Plug the hard disk power supply cable( D style) to power feeding input jack if need providing power to external equipment, please refer jumper setting section for the detail
5) Plug back the AC power cable, and power on PC
Chapter 3 Software Installation and Configuration
1) check the hardware detection by : lspci -vvvvvv
User should see the device information like this:
ISDN controller: Cologne Chip Designs GmbH ISDN network Controller [HFC-4S] (rev 01)
If user can not see that, please swap to other slots to try.
2) Checking the supporting packages
Note that if there is no kernel source in the system, user should install them. User can run yum again: yum install kernel-devel. It is time to check for the availability of some other packages:
rpm -q bison rpm -q bison-devel rpm -q ncurses rpm -q ncurses-devel rpm -q zlib rpm -q zlib-devel rpm -q openssl rpm -q openssl-devel rpm -q gnutls-devel rpm -q gcc rpm -q gcc-c++
If any of those packages is not installed, please install those packages by using yum
yum install bison yum install bison-devel yum install ncurses yum install ncurses-devel yum install zlib yum install zlib-devel yum install openssl yum install openssl-devel yum install gnutls-devel yum install gcc yum install gcc-c++
3) Downloading, unzipping and compiling driver
A. Download the stable version of mISDN, mISDNuser from http://www.misdn.org/index.php/Installing_mISDN, and copy the tar file to /usr/src/. Here，we are using mISDN-1_1_7 and mISDNuser_1_1_7. Users can get more details from mISDN.org.
Download asterisk from: http://downloads.asterisk.org/pub/telephony/asterisk/, here, we are using asterisk 1.4.11
B. Make links with kernel source:
ln -s /usr/src/kernels/2.6.18-8.el5-i686/ /usr/src/linux-2.6
Here, under /usr/src there is kernel source, user must create link linux-2.6 under /usr/src/. There are many files under /usr/src/
C. Compiling mISDN, mISDNuser and asterisk
cd /usr/src/mISDN-1_1_X make make install cd /usr/src/mISDNuser-1_1_X make make install cd /usr/src/asterisk-1.4.XX ./configure make menuselect Now you should enable chan_misdn in the Channel Driver Section and reinstall asterisk with "make install".
After that procedure you should have the current mISDN releases installed and the current chan_misdn with asterisk.
D. Modifying and loading modules for mISDN
If B400P is installed in the system, please edit the file: mISDN under /usr/sbin: cd /usr/sbin vi mISDN and change the line 277 like this:
elif ${LSPCI} -n -v -s "${line:5}" | ${GREP} "Subsystem" | ${GREP} "1397:b566\|1397:e884" > /dev/null
After modifying the mISDN file, the system will able to detect the B400P card. Now, user can run following commands under /usr/sbin:
./mISDN scan // detect Cards ./mISDN config // set configuration files under /etc/mISDN.conf ./mISDN start // start the drivers.
edit /etc/asterisk/misdn.conf to set a call routing.
run: asterisk –vvvvvvvgc to start up asterisk server
under asterisk console, run: misdn show stacks
if you can see the ports with active and up status, you will able to make calls.
Otherwise, please check the setting files and physical connections.
Chapter 4 Reference
Notes: Test environments: OS: Centos 5 Kernel version: 2.6.18-8.15 Asterisk version: Asterisk-1.4.11 mISDN version: mISDN-1_1_7 Hardware：OpenVox B400P
Status of LEDs : 1) LEDs will turn into red and blink if the drivers are loaded. 2) When a call is established, the LED will be turned into green status for very short while. 3) If ISDN cable plugs into the port, the LED will not blink, but in red color.
