My AS5300 (IOS 12.2(5)) is communicate to AS5300 (IOS 12.2(15), T12). The problem is that the call is disconnected every 5 second after connection.
Here is the ISDN debug informatiom:

Now, is really the IOS that causing this problem?
Secondly, is my Cisco disconnected the call due to "Unknown Service Discriminator"?
How can i locate the real root cause?
Is upgrading my Cisco IOS will solve the issue?
If yes, will this problem happen to all my existing termination via VOIP?
P/S: I don't face this problem at all to the rest of my termination via VOIP.
Please advise, Thanks.
