Asterisk Digit Manipulation

2010-09-17T15:28:00.004+08:00

Pattern Matching
To be able to allow people dial through Asterisk and have connect the caller to an outsite resources.

Pattern Matching Syntax
Pattern with underscore (_), tells the asterisk that we're matching on a pattern. After the underscore, we can use one or more of the following characters

X = Matches any single digit from 0 to 9.
Z = Matches any single digit from 1 to 9.
N = Matches any single digit from 2 to 9.
[15-7] = Matches a single digit from the range of digits specified. In this case, the pattern
matches a single 1, 5, 6, or 7.
. (period) = Wildcard match; matches one or more characters, no matter what they are.
! (bang) = Wildcard match; matches zero or more characters, no matter what they are.

Samples
_NXXXXXX = This pattern would match any seven-digit number, as long as the first digit was two or higher. This pattern would be compatible with any North American Numbering Plan
local seven-digit number.

_1NXXNXXXXXX = This one is slightly more difficult. This would match the number 1, followed by an area code between 200 and 999, then any 7-digit number. In the NANP calling area, you
would use this pattern to match any long-distance number

_011. = This pattern matches any number that starts with 011 and has at least one
more digit. In the NANP, this indicates an international phone number.

Outbound Dialing Capabilities in Dialplan
exten => _XXX,1,SayDigits(${EXTEN}) = SayDigits() application will read back to you the three-digit extension you dialed.

${EXTEN:x} = where x is where you want the returned string to start, from left to right.
exten => _XXX,1,SayDigits(${EXTEN:1}) = the SayDigits() application would start at the second digit, and thus read back only the last two digits of the dialed extension

How to Interconnect with others #2

2010-01-22T12:12:00.003+08:00

1. Above also solution diagram that can be use by user. Some good advantages is user will be enjoyed call Inter- branch for free.
2. But when people from Company make outsite call, we will pass the call to Asterisk2billing (A2B) engine for rating and etc.
3. Then, A2B passing the call to ITSP for call termination.
4. A2B keep CDRs and administrator at each Company can view his own CDRs
5. I'll will show some GUI on what administrator and user/customer can view at A2b later

How to Interconnect with others #1

2010-01-21T17:22:00.005+08:00

There is a few ways you can interconnect with other system using Asterisk. In this method, since I don't have E1/FXO/FXS card at my Asterisk system. Thus I am deciding to you my existing Cisco Gateway AS5XXX to interact with Asterisk via SIP protocol.

Listed below are the major call feature has been tested by using this kind of setup.
1. Fax to Email (Using E1 DID)
2. IVR (Time Base Routing)
3. Faxing out using Hylafax

A2Billing with Webmin

2009-12-24T12:02:00.007+08:00

1. Get the debian package( since i am using deb)
-> dpkg --install webmin_1.500_all.deb

2. Install dependencies
-> apt-get install libnet-ssleay-perl libauthen-pam-perl libio-pty-perl libmd5-perl

3. Once completed, try login your webmin using below URL
-> https://X.X.X.X:10000/

4. Done

Note: You need to change access port (10000) to something else, because 10000 also being use by Asterisk for RTP. That step must be done to prevent post clashing between those application

5. How to change??? edit below file
vi /etc/webmin/miniserv.conf

This is Step by Step upgrade process for my Elastix A2billing

2009-11-23T11:49:00.004+08:00

Step 1: Drop Database

[root@elastix agi-bin]# mysql -u root -peLaStIx.2oo7

Welcome to the MySQL monitor. Commands end with ; or \g.

Your MySQL connection id is 2866

Server version: 5.0.45 Source distribution

Type 'help;' or '\h' for help. Type '\c' to clear the buffer.

mysql>

mysql> DROP DATABASE mya2billing;

Query OK, 51 rows affected (1.11 sec)

mysql> quit

Bye

Step 2: Uninstall a2billing

[root@elastix agi-bin]# rpm -e elastix-a2billing

[root@elastix agi-bin]#

#mkdir /usr/local/src/a2billing

Step 3: Download a2billing tar package and create under folder /usr/local/src

[root@elastix agi-bin]# cd /usr/local/src/a2billing/

[root@elastix a2billing]#

[root@elastix a2billing]# wget www.asterisk2billing.org/downloads/A2Billing_1.4.1.tar.gz

14:58:54 (163 KB/s) - `A2Billing_1.4.1.tar.gz' saved [9658300/9658300]

[root@elastix a2billing]#

Step 4: Untar tha package

[root@elastix a2billing]# tar zxvf A2Billing_1.4.1.tar.gz

Step 5: create a MySQL database (mya2billing) for the billing software.
The file a2billing-createdb-user.sql includes a script that creates the database with the correct access control users and permissions.

#cd /usr/local/src/a2billing
#mysql -u root -p < DataBase/mysql-5.x/a2billing-createdb-user.sql
(the elastix mysql root´s password is: eLaStIx.2oo7)

The script with create a database, username and password with the following default values

Database name is: mya2billing
Database user is: a2billinguser
User password is: a2billing
After creating the database structure, we will create a set of tables and insert some initial basic configuration data

[root@elastix a2billing]# cd /usr/local/src/a2billing

[root@elastix a2billing]# mysql -u root -p <>

Enter password: eLaStIx.2oo7

[root@elastix a2billing]# mysql -u root -p mya2billing <>

Enter password: eLaStIx.2oo7

[root@elastix a2billing]# mysql -u root -p mya2billing <>

Enter password: eLaStIx.2oo7

Step 6: Copy the a2billing configuration file to /etc folder

[root@elastix a2billing]# cp /usr/local/src/a2billing/a2billing.conf /etc/

Step 7: 6) Edit the file.
#vi /etc/a2billing.conf
Change the "database" paramenter as follow, the other paramaters must remain unchanged:

[database]
hostname = localhost
port = 3306
user = a2billinguser
password = a2billing
dbname = mya2billing
dbtype = mysql

Step 8: Create the additional files and setup the correct owner:

Create the additional files and setup the correct owner

#touch /etc/asterisk/additional_a2billing_iax.conf
#touch /etc/asterisk/additional_a2billing_sip.conf
#echo #include additional_a2billing_sip.conf >> /etc/asterisk/sip.conf
#echo #include additional_a2billing_iax.conf >> /etc/asterisk/iax.conf
#chown -Rf asterisk:asterisk /etc/asterisk/additional_a2billing_iax.conf
#chown -Rf asterisk:asterisk /etc/asterisk/additional_a2billing_sip.conf

Step 9: Install the sound files
[root@elastix a2billing]# /usr/local/src/a2billing/addons/sounds/install_a2b_sounds.sh

Cisco IP Phone upgrade to SIP

2009-10-30T16:47:00.002+08:00

I've upgrade my Cisco IP phone 7940 and 7960 model to SIP and use with my asterisk server. I'll describe it here on how to do.

Prerequisite:
1. You must have TFTP server software. I am using Cisco TFTP. Or you can use linux server to host your Cisco config file.
2. Of course Cisco IP Phone OS (ie : P0S3-05-0-00.sbn)
3. Check your TFTP directory and put 3 important file
a. Cisco IP Phone OS
b. .CNF (ie SIP000628F0FCB5.CNF)
c. OS79XX.txt (Containing P0S3-05-0-00)

Then we move to Cisco IP Phone
1. You must unlock your Cisco IP phone by pressing **#
2. Go to Network and set DHCP to No
3. Go to TFTP server setting and set your TFTP server IP.
4. Everything must be save
5. Restart your Phone

Hope thats can help you

A2billing as Wholesale

2009-06-30T13:17:00.001+08:00

You need to modify some a2billing.conf to use for wholesale.

a2billing.conf

; enable the callerid authentication
; if this option is active the CC system will check the CID of caller
cid_enable = YES

Note: By default is NO. If you set to YES, user will automatically promted by IVR " you have $$ dolar " meaning that

system checking CallerID.

For wholesale setting
#####################

; Play audio - this will disable all stream file but not the Get Data
; for wholesale ensure that the authentication works and than number_try = 1
play_audio = YES

=> Change to NO

; number of times the user can dial different number
number_try = 3

=> Change to 1

; if YES it will use the DNID and try to dial out, without asking for the phonenumber to call
; value : YES, NO
use_dnid = NO

=> Change to YES
