Hi all,
Pls help.
Scenario:
2 AS 5300 acting as the originating and terminating gateway on each
side of the network. The originating AS5300 is connected to the PSTN switch
( SW A ) using PRI signaling while the terminating AS 5300 is connected to
the PSTN switch ( SW B) using R2 signaling. The customer will dial a
specific number to access the SW A and then enter the account and pin
number. After the authentication, there will a beep tone follow by the
message which prompt the user to enter the destination phone number.
For a normal scenario,
After the entering of the destination phone number, there will be ringing
tone. When B-party picked up the phone, there will be a second beep tone
which will trigger the billing system to start the billing.
However, what actually happens is that,
After the entering of the destination phone number, just right before the
ringing tone, there is a "click" sound immediately before the ringing tone
which undesirably, trigger the billing system. This creates problem because
even before the call get connected, the customer has already been charged.
The Attempted Solutions include
1. Program the progress indicator at the terminating gateway's dial-peer
2. check the output of the "debug isdn a931" (looks fine)
However, the problem still haven't been solved. Please help.
