We need to use the RV_CIDNUMBER value.
From the help file, we know
On many telephone systems the Caller ID information is sent between the first and the second Ring. Hence it is usually necessary to set the line to answer after the second Ring if this Result Variable is to carry any information. Select "Line Device Config" from the View menu when running VoiceGuide to set the Ring count.
But not sure what does it mean.
I found on some posts in forum that this might help:
Is it correct?
FYI we are using vg7.4 with dialogic board D4PCIU4SEW on some environments and also HMP on some others.
Is there a way to set "$RV_CIDNUMBER" inside the script for testing purposes?
We test always using phonerlite, and that gives us something like "SIPPER@IP_ADDRESS" as cidnumber, but while testing it whould be good if I can set it to something like "77777".
