Need to Deploy Logical Partition on ISR 4321 (India)

Hello,

 

I have a CUCM Cluster (Pub & Sub) , UCCX cluster (HA Mode) & 2 Voice gateways ISR 4321 (All at one location)

 

We have two PRI terminating, one on each Voice Gateway (ISR 4321) means both the router has one PRI terminated on it.

 

Configured SIP for PRI  PSTN call routing

 

IP Phones we have are majorly 3905 corporate and 7800 series IP Phones are for contact centre agents. (All users are at one location there are no remote locations)

 

Now we are planning to get one SIP Trunk from ITSP for ISD calling, which will get terminated on one of the ISR 4321 router.

 

So now my question is can we configure Logical Partitioning to avoid Toll Fraud between SIP Trunk and PRI.

 

Please note that SIP Trunk and PRI both are terminated on same router.

 

Thank You,
