Hi Brian,
I would change back their pattern as they are testing you on the following concepts. When the call comes into the GW on CUCM, the prefix values configured will be added to the front of the number. In order to figure out how you will prefix this you need to look at the debug isdn q931 and work with what you've got. Meaning, if you are receiving a Subscriber number 2059432785 then you need to manipulate the Subscriber prefix. This will effect what you will see in the Missed Calls and solve part 2. Now, the phone's device pool has a calling party transformation calling search space applied to it. This will be used incoming on the phone and determine how you will localize the calls on the screen. You will need to have a Calling Party Xformation pattern that will manipulate it back down. This effects the screen and nothing else. I'm trying not to give the answer as understanding these concepts is key and you can solve this in 2 mins once you understand how these all work together. Try and fool around with these values and let us know how it goes. Hope this helps, Jeff From: ccie_voice-boun...@onlinestudylist.com [mailto:ccie_voice-boun...@onlinestudylist.com] On Behalf Of Brian Rudy Sent: Monday, December 20, 2010 8:04 PM To: ccie_voice@onlinestudylist.com Subject: [OSL | CCIE_Voice] Volume 2 Lab 5 Task 2.3 I have concluded the "preceding 0 that comes in from the PSTN" was incorrect in the WB and PG? These are the tasks where it talks about having +44 020 5943 2785 in the missed/received calls directory. First, I was not getting the 0 or National in my debug isdn q931 on inbound calls from the 2nd Button on PSTN Phone to HQ Phone 2. I changed the translation pattern on the PSTN router FROM rule 2 /^2059432785$/ /\0/ type any subscriber plan any isdn TO rule 2 /^2059432785$/ /0\0/ type any national plan any isdn However, if i strip the 0 (National Number - 44:1) at the HQ Gateway and Globalize the Number, then how is going to show in the missed/received calls directory as +44 020 5943 2785? Any insight to this is greatly appreciated! Brian
