You need to collect the

You need to collect the detailed callmanager traces and look at the Digit Analysis ( DA ) portion. The list of partitions in the 'pss' field should contain the partition of the Route pattern and further the 'RouteBlockFlag' in the DA DA will say 'Route this pattern' or ' Block this pattern ' , here is an example

|StationD - stationOutputActivateCallPlane tcpHandle=0x53563d0
   |Digit analysis: match(fqcn="", cn="1000", pss="", dd="")
   |Digit analysis: analysis results



how did you run the DNA, with

how did you run the DNA, with Analyzer option or with the specific phone device?

if you ran with the analyzer option, did you select the correct CSS and complete dialed number including the access number?


you should be able to check and match the route pattern with the number you are dialing.


if the device CSS doesn't contain the partition of the route pattern, you may see that call blocking too.
