If we have a IP phone number 100 but unregistered and have a route pattern 100 throw to a siemens, Why the call doesn't go to this route pattern?

Assuming there is no CFUR or any other call forward behavior configured in that DN, simply because that's NOT how call routing works, you won't automagically hunt through other DN/patterns.
If there is a call forward behavior in the DN, then you'd need to look at your CSS/partitions for call forward to make sure it works.

Hello @Faisal.Saoud
Basically CUCM uses Closed Match routing process to check where to route de call based on Partitions available on your CSS and with a draw solve using it's order.
Example:
CSS_PSTN: PT_Extension, PT_PSTN
Directory Number 100, Partition: PT_Extension
Route Pattern 100, Partition: PT_PSTN
My directory Number CSS: CSS_PSTN
As soon as I dial 100, CUCM checks that you have in your CSS 2 Matches exactly 100: The Directory Number and your Route Pattern.
As soon as your PT_Extension are your first in order and we have a draw on routing decision, CUCM will route the call to directory number (even if this extension are unregistered).
When call routed to this number, you can setup a Call Forward Unregistered Number to 100 with CSS which contains only PT_PSTN to "force" routing to your Route Pattern if this number are unregistered.
Alternate option are change Partition order if you want to neve matches directory number from CSS_PSTN.

If I want to configure CFUR on the lines and need to forward each number in this bulk 1xx to forward to the opposite same extension on the route pattern (1xx), how can I do that?

Hi,
My understanding and based on your second post is that you have a Cisco IP phone on extension 100 and a phone registered to a Siemens PBX also on extension 100 and you want the call to route to the Siemens phone if the Cisco phone is unregistered?
One way might be adding a prefix to your Route Patterns on CUCM which target the Siemens PBX so that they are different number range to your Cisco extensions, e.g. Siemens extension on "2100", set the CFUR value on the Cisco phone to 2100. You would probably need to route the "2" from CUCM to the Siemens PBX and then configure the Siemens to drop the "2" prefix when it arrives so that it knows to route it to the right extension.

Yes you can do that via bulk import/export by changing to same number on a different CSS which matches Route Pattern only.
ex:
Directory Number: 100
Partition: PT_Extension
CSS: CSS_PSTN
CFUR Destination: 100
CFUR CSS: CSS_SIEMENS_FORWARD
CSS_PSTN: PT_Extension, PT_PSTN, PT_SIEMENS
CSS_SIEMENS_FORWARD: PT_SIEMENS

If you want to use CFUR you can use a wild card pattern XXX to use the same digits as in the directory number.
What I think is a better solution is to setup SNR to extend the call in parallel to the extension in the Siemens PBX when there is a call made to the extension in CM. Have a look at the Feature and Services configuration guide for more details on this.
