Asterisk can use global and channel variables in command arguments. To reference a variable in the dialplan (extensions.conf), use the following syntax: ${foo}, where foo is the variable name. The variable name can consist of any sequence of digits and letters, and must start with...
There was a need to configure Asterisk for making calls via a 3G modem. After a bit of searching, I found a module called chan_dongle. We have Asterisk 11 running on Ubuntu.

You can copy the commands below into the console and lean back in your chair while waiting. svn co svn.digium.com/svn/asterisk/branches/1.6.0 asterisk cd asterisk ./configure && make && make install && make samples && make config cd…
1. Configuring GOIP. It is assumed that the gateway has the factory configuration. Insert the SIM cards into the gateway. Power it on. Now, access the gateway's web interface. To do this, connect GOIP to the local network using an Ethernet cable. There are two ways: 1) Through the "PC" port. By default, it…
in the standard format: ; And here’s how the same context would look in ael syntax: So, the differences are clear. For me, one of the main advantages of ael is the readability of the configuration file: even in this small abstract example, it’s evident that reading and understanding…

Description: GotoIfTime(<times>|<weekdays>|<mdays>|<months>?[context|]extension|]pri) If the current time matches the specified time interval, then the call is transferred to the specified extension. Each element for time specification can be set as the '*' character (always matches) or as an interval. If the current time does not match the specified…

String manipulation functions The ${LEN(foo)} function returns the length of the string foo. For example, exten => 100,1,Set(Fruit=pear) exten => 100,2,NoOp(${LEN(Fruit)}) exten => 100,3,NoOp(${LEN(${Fruit})}) The first NoOp command should display the value 5 (the length of the string "pear"). The second NoOp command should display the value 4...
Channel-Specific Predefined Variables Below is a list of channel-specific variables set by Asterisk itself, whose values you can use in dialplans. Unlike user-defined variables, variables defined by Asterisk are case-sensitive. ${ACCOUNTCODE}: Account code, if…

Configuring fax (reception) Ideally, I would like to set up both reception and sending through Asterisk's built-in fax module, but sending currently raises many organizational issues (such as how to specify the number, convert formats, etc.). Here, I will cover the configuration for receiving faxes. The company Digium…
