CDR fixed if anyone interested.


is an incomplete fix, it is not possible to filter the number called for “portion” of number, as it is not much use the CDR



It is ok, just read description.


I wrote a number called a non-calling number.
What you highlight I know, unfortunately only applies as a filter for calling number.



You right, they do not allow to use any . or x to fill blank in Callee Number. Bug or by design problem i confirm.
It was not working on older soft (18.12) so maybe GS is unaware of this problem.


reported to Helpdesk, they confirm that it is a lack on their part



I have updated to for my UCM6104 and UCM6108. After firmware update outbound route and inbound route for both devices are not working. Any suggestions. Thanks.
