[cisco-voip] Avoiding bounces with overlapping ranges

[Lelio Fulgenzi]

Yes, that took me a while to understand when first explained to me, but you hit the nail on the head. 

If you are sending calls to anything off the system (I refer to this as off-box vs off-net) that should be in a separate partition than anything that resides on the system. This could be a PBX, another cluster, etc. 

Add this partition to the CSS of all devices except the inbound trunk that those calls are sent to. 

We had dead air for years when an invalid number was called until we resolved this because our PBX defaulted to send everything else to the CallManager.

Do not let your PBX trunks on CUCM see themselves. That is do not let the CSS on the trunks see the route patterns that send calls back to the PBX.

So as we’re migrating off of our antique PBX we have a problem with bouncing calls. 



PSTN -> CUCM -> Gateway(MGCP/QSIG) -> PBX 



Call comes in for extension 8011, its not on the CUCM, there’s a rule for unknown extensions in the 80xx range to go to the PBX. The PBX gets the call, doesn’t show it on it’s list of ports, then sends it up the chain (back to the CUCM)…then the cycle begins. It eventually fills up the ports on our Gateway and they finally get a busy signal (3-10 sec later) and the ports clear again. 



I’m not about to mess with PBX any more than I have to, so without “fixing” the PBX, how can I adapt the CUCM to be smarter with specific number overlaps?
