UUI data over ISDN PRI

[vsunh]

I am trying to send UUI data over ISDN PRI line which is terminated on dialogic. I am using envox script functions "send UUI" for the same. Basically envox script makes an outbound call using make call block & sends UUI using UUI Block & the receiving IVR channels is trying to extract the UUI data.

Can some one suggest as how to acheive this?

1) What is the problem you have encountered?

2)What ISDN protocol are you using? User to User Information is not widely available.

3) What are you trying to achieve?

Test set Up :-
ISDN PRI ( DID - 100 levels) is terminated on the Dialogic D600 JCT Board.Envox Application on channel no 1 is making an outbound call thru this PRI tunk & trying to send UUI information "abcdef" over the network.
The outbound call lands on channel no 3 & script running on the same is trying to retreive the UUI value "abcdef"

Problem:
The UUI field is always showing blank

Protocol Used :
The protocol used is dialogic Global Call Protocol.

So the PRI is a real PRI? What protocol (AKA Switch and Variant) is it? Where are you located?

If it is not a real PRI then what is emulating the PRI at the other end of the simulation?

So you are calling from B1 to B3 for your tests?

What real ISDN protocol is "Dialogic Global Call Control" supposed to be emulating?

Does the dialogic documentation indicate they support UUI?

Yes, Dialogic Platform supports UUI. It is a real DID PRI.

but the problem remains same, i an unable to send UUI/ IE information.

For your information, let me share with you the Envox Application block which can send UUI information:

The SendUUI block is used to send messages to any remote ISDN terminal connected to the Envox system through any regular ISDN telephone network.Messages are sent to the remote terminal over the ISDN data channel using the User-to-User Information protocol (an integral part of the ISDN signaling standard).
When creating a UUI dialog with a remote ISDN terminal, the SendUUI block is used for sending data.

In order to also receive data from a remote terminal, first enable UUI signaling by using the EnableFeature block or by setting the @IsdnUUIEnabled variable to 1. As soon as a UUI message is received, the UUIReceived system event will create an interrupt in script execution. The UUI message received will be available in the @IsdnMessage system variable.

Message. Define the message to be sent to the remote ISDN terminal (maximum 131 characters).

Protocol discriminator. Set the protocol discriminator of the UUI sent from Envox as part of the SETUP message:

$UUIProtocol_Q931. Set to 8 as defined by the Q.931 user-network protocol. This is the default setting.

$UUIProtocol_IA5. Set to 4 as defined by the IA5 character protocol.

$UUIProtocol_UserSpecific. Set to 0.

Send. Choose when the message is to be sent:
Immediately. The message is delivered instantly.
During call setup. The message is delivered as soon a new call is received or made.
During call disconnect. The message is delivered as soon as the current call is disconnected.

I am selecting
message = 01010
Protocol discriminator = $UUIProtocol_Q931
send = During call setup

It is unlikely that your PRI supports User-to-User Information. You should check this with your PRI provider before you spend much time on this.

Most Telco's are very wary of the ability of customers to send ANY data without a call completing since they cannot charge for an incomplete call.
