PG IVR - "Overflow on No reply" doesn't work

[CW]

System Release: R6.1.1-f2.502-5


I have an IVR PG which contains about 60 IVR accesses. If a call is being routed to this IVR PG it will ring at one of the IVR accesses. If the rang IVR access does not pickup this call, it will be redirected to the next available IVR access of the same IVR PG after the "ringing rotation timout" (assumming that there is some problem with that IVR port), which I have set it to 10 seconds. If the call still hasn't been pickup after 20 seconds (assumming that the second IVR port also has some problem), I want the call to be overflowed to another pilot (connect to Agent PG) so that the agent can response to the call.

Based on the above, I have set the IVR PG's with the following:
=========================================
Ringing Rotation Timout : 10 seconds
Overflow on no reply timer : 20 seconds
Overflow on no reply address: 7200 (my agent group pilot number)


Ringing rotation timout works but the call never overflow to 7200 after 20 seconds. I had tried using different timer like 5 seconds for the overflow on no reply timer but still it didn't overflow to 7200. I had also tried to change the overflow on no reply address to a normal analogue extension number but also it didn't work. I wonder this is normal or it's a software bug in the release.

Any expert can advise me on this? Please help. Thanks in advance.

CW,

Let me clarify smth. You have 60 ports for your IVR, so I believe you have 2 IVR PGs connected to the same queue with equal Call distribution priorities. If it sounds right, can you check in CCS if call routed to these PGs rotates between 2 PG every 10 sec, in this case call never gets 20s of continious ringing in the same group. Just an idea.

Let me know if it helps. I have one node with similar setup.
