Hi all We have SIP trunk between CVP and CUCM
I want to block some calls based on spesific pattern
When a call is transferred from CVP to CUCM like 8XXXX52X , I want to block this pattern of calls
How can I do this on Route Group or Route list or trunk?
You can use the same method used for MGCP call blocking for this, there's plenty of references on CSC, and even a doc on it, you simply need to search for it.
I'm assuming you want to block based on ANI for inbound calls to CUCM, if this is for outbound, then use block this pattern under the RPs.
Then it comes down to what the inbound CSS from the trunk allows CVP to reach, simply adjust as necessary.
I cant change CSS or pattern, it will affect lots of people in device pool. Also we re using HCS system.We can't change it.
I just need to change the dialed number based on spesific pattern
