Problem with Fallback on BCM

[bequi]

We have a problem with a Fallback on BCM50 (R2 and R3).

Well, i'm not sure that be a problem, or a "philosophy of design".


I have a BCM50 with 2 Voip trunks, and a "BRI MBM". The routing and scheduling is configured correctly.
I have 1 emergency extention (emergency DN), and that should be the only one that can be use the Fallback (BRI MBM). The other extensions (normal DN) shouldn't use the BRI module (in theory).


If i have the 2 IP-trunks busy, and a normal extension (normal DN) tries to realize a call, it receive a message "No free lines". That's correct, and is that we are looking for.
If the "emergency DN" tries the same (with the 2 IP-trunks busy), the call will be realized through the BRI MBM. That is correct.

But if the IP-trunks are "down" (the cable LAN is out for example) the normal extention can realized call normally through the BRI MBM. That is a problem, the "normal DN" shouldn't use the Fallback, only the "emergency DN".

Somebody has an idea to restrict the second scenario?

Thanks in advance.

Sorry I am not up to date on this type of senario as i have never done this.

But try changing the control set for the extns that are controlled by the routing srevice.
Suggest you give the EMG extn a new control extn for the routing service so as you dont have to go to all the Normall extns and change them.

This might JOG the Brain into thinking of something else

Ensure the "normal DN" does not have access to the line pool for the BRI's in the set configuration.

Thanks for the answer, we have tried it, but the result is the same. I changed the control set, even i deleted all DN on "Line pool A" (the Bri's Pool), but if you link down the LAN, you can call with BRI.

SupportDude:
Thanks.
Yes i'm sure, even i deleted all DN from "Line Pool A"


Thanks for answers.

I keep on the looking for the answer....

Are you using Scheduled Routing Service?
Are you using multiple routes under the schedule, or 1 route for the schedule and then overflowing to Normal for your fallback?
