This is the Analog Display Services Interface Configuration file for Asterisk. (Not to be mistaken with DISA, which is something completely unrelated).
1.1. Introduction to ADSI:
The file is located in the /etc/asterisk/ directory.
ADSI (Analog Display Services Interface) is a protocol for enabling alternate voice and data services over the analog telephone network, such as sending data to a display at the ADSI phone
It also allow for running simple interactive scripts on the ADSI phone, such as Call Waiting Deluxe, an application that displays the name and number of an incoming call while you are on the phone.
Not only will the phone display the number, it will also ask you what to do with it, including switching to the new call, forwarding the new call to your voice mail, putting the new caller on hold, playing a recorded message, or dropping the current call and switching to the new call.
Other ADSI applications include:
- Visual voice mail: the display of telephone voice mail menu options and a list of your voice mail messages
- Visual directory: a service that allows you to locate the telephone number of an individual or business and, possibly at extra charge, to download the address of that individual to your screen phone
- E-mail browsing: allowing you to send and receive e-mail messages via an ADSI-enabled device.
- Schedule-based services: faxing abilities, notification of incoming e-mail messages, home banking, ticket purchasing, and access to train and plane schedules.
1.2. Prequisites
- Asterisk
- a configured TDM card, fxo card or combination of channel bank and E1/T1 card.
- ADSI Capable phone
1.3. ADSI capable phones:
- Sayson/Aastra 390/480e
- Cybiolink P-1 ADSI analog phone
- Nortel Vista 350/380
(If you know more, please leave a comment and we will add them).
1.4. Configuration of asterisk for ADSI
Saddly, we don't have an ADSI phone in our lab, so all the information here is gathered on the internet and untested.
The main ADSI configuration file is called ADSI.conf, a sample ADSI script is included in the asterisk sources as asterisk.adsi.
To use ADSI, you need to enable ADSI on this specific zaptel line.
(So first you will need to read up on how to configure zaptel for your card and then enable ADSI on the channel your phone is connected to by adding the line adsi=yes to the configuration for this channel in zapata.conf.
; ADSI (Analog Display Services Interface) can be enabled on a per-channel
; basis if you have (or may have) ADSI compatible CPE equipment
;
;adsi=yes
I don't think you need to touch anything in adsi.conf, the sample configuration file looks as the snippet below:
;
; Sample ADSI Configuration file
;
[intro]
alignment = center; alignment on the screen, valid values are: l(eft), r(ight) i(indent?). All others are recognized as centered.
greeting => Welcome to the ; Some greeting, don't know when its shown on the phone
greeting => Asterisk
greeting => Open Source PBX
maxretries = 3 ; number of times to retry sending to the ADSI phone
[speeddial]
--please look at res_adsi.c
For the speeddial option, you will need to look at the res_adsi.c source code, i suppose its name,number or number,name.
1.5. ADSI scripts
Asterisk comes with two ADSI scripts included,
asterisk.adsi
telcordia-1.adsi
These scripts need to run on the phone, asterisk can upload them to the phone for you.
To do so, you will need to create a specific extension, which will call the ADSIProg application. When you call this extension with your phone, asterisk will upload the script to the phone.
If your phone has multiple slots, you can upload one script per slot. (each slot will have a different FDN).
1.6. Other ADSI related features
1.6.1.: Voicemail
The comedian mail has some support for ADSI, if you want to use this with your phone, you will need to alter the codes again, but this time in the sources for comedian mail.
static char *adapp = "CoMa"; --> this value is the FDN as seen before
static char *adsec = "_AST"; --> this value is the security code as above.
This means that if you change the brand of phone, you will need to alter this again and recompile. And you probably will be unable to use different brands of phones at the same time.
1.6.2.: Send text to an ADSI phone
If you have a look at this google cache, you will find an application to send messages to your ADSI phone from the asterisk dialplan.
1.6.3.: Call Parking
Asterisk can send some information to your ADSI phone when you park a call, to enable this, edit features.conf and type the line adsipark = yes
