You need to configure your carrier on your asterisk box so you can make a call. So you need to be able to setup routes and trunks.
The software is a Linux bash script that reads in a text file and generates .call files. The call files are copied to a location where asterisk picks them up and executes them.
Call files are explained here:
The text file that the bash script reads in is very simple. Its just the number to dial, the trunk to use, the outgoing cli to pass to the carrier, the context, the extension, if the call is to be done by it self or simultaneously with other calls and the hold time.
To generate the text file its easy to use excel. One line in the text file is one call. You can have a text file with thousands of lines.
The number of simultaneous calls is only limited by the agreement with the carrier you have, and how much bandwidth you have.
You can make a lot of simultaneous calls from a home type ADSL line with no problems, but be careful of others using the ADSL for torrents or BBC iPlayer downloads and the like!
To get the dialer software please use the link to apply for a rate card and test numbers, and we will include the dialer for free.
Platforms and hardware:
The software will also run on Raspberry Pi.
It can be used with Huawei USB 3g Modems with sim cards in to make calls and send text messages.
You need to be careful with power consumption and get a powered hub if you want to have multiple Huawei devices dialling at the same time.
Or you can use GOIP VoIP gateways, you will find them on eBay.
