What Is Asterisk?
Asterisk is a complete PBX in software. It runs on Linux and provides all of the features you would expect from a PBX and more. Asterisk does voice over IP in three protocols, and can interoperate with almost all standards-based telephony equipment using relatively inexpensive hardware.
Asterisk provides Voicemail services with Directory, Call Conferencing, Interactive Voice Response, Call Queuing. It has support for three-way calling, caller ID services, ADSI, SIP and H.323 (as both client and gateway). Check the Features section for a more complete list.
Asterisk needs no additional hardware for Voice over IP. For interconnection with digital and analog telephony equipment, Asterisk supports a number of hardware devices, most notably all of the hardware manufactured by Asterisk's sponsors, Digium™. Digium has single and quad span T1 and E1 interfaces for interconnection to PRI lines and channel banks as well as a single port FXO card and a one to four-port modular FXS and FXO card.
Also supported are the Internet Line Jack and Internet Phone Jack products from Quicknet.
Asterisk supports a wide range of TDM protocols for the handling and transmission of voice over traditional telephony interfaces. Asterisk supports US and European standard signalling types used in standard business phone systems, allowing it to bridge between next generation voice-data integrated networks and existing infrastructure. Asterisk not only supports traditional phone equipment, it enhances them with additional capabilities.
Using the Inter-Asterisk eXchange (IAX™) Voice over IP protocol, Asterisk merges voice and data traffic seamlessly across disparate networks. While using Packet Voice, it is possible to send data such as URL information and images in-line with voice traffic, allowing advanced integration of information.
Asterisk provides a central switching core, with four APIs for modular loading of telephony applications, hardware interfaces, file format handling, and codecs. It allows for transparent switching between all supported interfaces, allowing it to tie together a diverse mixture of telephony systems into a single switching network.
Asterisk is primarily developed on GNU/Linux for x/86. It is known to compile and run on GNU/Linux for PPC along with OpenBSD, FreeBSD, and Mac OS X Jaguar. Other platforms and standards-based UNIX-like operating systems should be reasonably easy to port for anyone with the time and requisite skill to do so. Asterisk is available in the testing and unstable Debian archives, maintained thanks to Mark Purcell.

FAQ for isdn4linux: Features SMS
FAQ for isdn4linux: Features: "3.11 feature_sms: Can I send SMS (short messages) to my mobile phone via ISDN?
Yes, you can use the program yaps to do this. However, due to some pecularities in the SMS-callcenter's ISDN connection, you have to compile the kernel with the options Disable send complete and Disable sending llc. Please note that mainly German providers support sending SMS via ISDN connection, in other countries this might not work. Dutch as well as UK SMS callcenters seem to not support this feature. Please let me know if you have additional information on this. A useful sample config for yaps you might find on: http://www.tnt-computer.de/linux/yaps-suite1-1.tgz
Another program to send SMS is asterisk. Have a look at: http://www.asterisk.org and http://www.voip-info.org/wiki-Asterisk cmd Sms. One advantage over yaps is that it can also receive SMS, for Germany (you have to register for this first by sending a specific SMS - otherwise the SMS will be communicated to you by an automated voice call).
Yet another program to send SMS is smsclient. You can find it on: http://www.smsclient.org."
