Hello Guys,
One of my reception has a requirement when she is busy, she will forward all calls to an external number (charged on minute). Is it possible on CUCM to forward all calls for external calls only, while internal calls will not.
Thanks,
Tuan

Hi Tuan,
This can be done by using the "Route next hop by calling party number". For example:
If the extension range on your CUCM is 4 digit 1XXX and the calling number being presented to CUCM from PSTN is in \+.! format and your operator with extension 1000 want the call to be forwarded to a PSTN number is the call came in from PSTN.
Configuration required would be 3 partitions:
PT_Internal
PT_Outside
PT_CFD_External
Calling search space:
CSS_ExternalCFA: PT_CFD_External
CSS_ExtForwardCheck: PT_Internal & PT_Outside
Translation patterns required:
1. 99999 (Just a dummy number)
This TP will have CSS_ExtForwardCheck and partition PT_CFD_External assigned to it,
Make sure the " route next hop based on calling number ".
2. XXXX (for internal extensions)
This will have PT_Internal to it
You can change the called party transformation to the number you want to forward if an internal user calls in.
3. \+.! (for outside callers if the number being sent by provider is in E.164 format)
This will have PT_External assigned to it.
Assign it an appropriate CSS.
Apply the appropriate called party transformation pattern to the PSTN number where the call should forward to.
Setup would be:
PSTN caller calls reception >>>> Extension 1000 >>>>> CFA >>>> 88888 (Translation pattern) --> This TP will check the calling party number and based on that forward it to tp >>> \+.!
One particular used cased scenario of this is in blocking the calls on CUCM based on calling number. You can refer to the discussion below:

Hi,
You can use "Forward Busy External" & "Forward No Answer External" under call forward settings on the extension to achieve this.

Hi Aseem,
Yes, I know this option. Unfortunately, the user doesn't to have the delay for the calls to be busy or no answer.
For example, when she is not in the office, she want to forward all calls to external number without delay.
Thanks,
Tuan
