asterisk users - May 2003 - Questions about AGI and Wildcard boards

Hello all :) 

I've just been handed a project that I need to get working pretty quickly.
Basically I have four "analog DID trunks" for incoming only calls
coming in.
I know that these are Loop start with Wink start, and that after wink they 
send a 4-digit id number.  Is this something that the Wildcard boards are 
able to handle and that Asterisk could interpret?   The digits are sent 
before any phones attached to the circuit ring. 

Secondly, when the receptionists get calls, they are required to make notes 
online about what the call was about, who it was from, etc.   I realize that 
AGI is probably the way to do this, but would this provide a means of 
synchronizing between the server running * and the workstations?   I have no 
problems writing this as a socket based app, but don't know enough about * 
yet to determine if this is feasable. 

It would also be nice to be able to selectively record any or all calls 
coming in. 

Basically this system is supposed to replace the current paper and pencil 
method of taking calls, while allowing monitoring of the operators. 

Thanks!
Mike Atkinson

Hello,

That functionality is supported with T1 boards. With FXO boards its not
supported.

Martin,

Which functionality is only supported with T1 boards?

Thanks!
Mike

Wink-start analog with callerid/DID

Back when I worked at the phone company it was a common occurrence to 
multiplex analog DID trunks. So, analog DID trunks should be able to 
interface * after they are multiplexed using a channel bank. (the 
channel bank needs to support DID trunks!) The T1 side of the channel 
bank would interface with a T100P or T400P board from Digium.

Phone companies provide DID trunks from the trunk side (not the line 
side) of a telephone switch. Nowadays these are only provided in a 
digital format (part of a T1). In order to deliver them as analog DID 
trunks the phone company will use a channel bank, usually back in the 
central office to convert them. As analog DID trunks they require a 
cable pair for each trunk. This would be your 4 pairs.

For this part my expertise is starting to fail so if anyone sees 
anything wrong please jump in.

Do you get dial tone from the analog handset?
Can you make calls with an analog handset?
You should be able to do these for pots lines or analog DID trunks 
which use loop start. Ground start  DID trunks would not give you dial 
tone.

For more information see http://www.ct-labs.com/Dr%20C/q47.htm

Will the handset ring if called?
I don't believe it would for trunks.

Regardless, after a call is received, the phone company would then 
forward digits for the extension that was dialed. These should be in 
the form of DTMF tones (Dual Tone Multi Frequency).

Good luck!
