I am getting alerts generated for a gateway that is unlikely to be encountering "all channels busy" situation (which I believe is the only cause for this alert). Now I accept that there are obviously high utilization periods, that calls can use multiple channels if they are re-direct to an extenal source etc. etc. But are there any other circumstances that could generate this alert (insufficient DSP's to address channels etc.) or anyway I can get an further details on this error ? I am looking at the RTMT console, and can only see RouteList name and no further info (CM 4.02 + RTMT 4.0).
I was little suspecious about this myself on my last implementaion with CCM 4.1(3), I found out that the service provider allowed only for 6 outbound calls on the PRI per some old agreement with the cusomer that no one remembered. Check with the SP to make sure this is not the case.
Also, I would recommand turning on a PerMon trace for few days and monitor conurrent calls on the PRIs.
Number of RouteListExhausted events exceed 0 within 60 minutes
If no, please post the exact error.
If yes, then the RouteListExhausted messages indicate that CallManager was unable to send a call to those Route Groups in a Route List. This is usually as a result of no B channels or ports being available on a gateway for routing a call.
Is there a way to know which RouteList is concerned ? Because I have an H323 gateway and several PRIs, so I would like to be able to know which one is concerned. I'm pretty sure it's the H323, but it would be very useful to know if I'm running out of B channels also.
