Some customers require that external calls to a hunt group or an extension be routed differently than internal calls to the same destinations. There is a command in IOS that can help with this.
For example, assume the following:
- Customer has one UC520 with 3 extensions (200, 201 and 202)
- 200 is the receptionist number, while 201 and 202 are individual numbers.
- Customer wants calls coming from the outside that ring 201 or 202, to be forwarded to 200 is these calls aren't answered.
- Internal calls to 201 or 202 should not be forwarded.
The above can be achieved with the "forward local-calls" command in the following manner:
!
ephone-dn 20 dual-line
number 200
!
ephone-dn 21 dual-line
number 201
no forward local-calls
call-forward noan 200 timeout 30
!
ephone-dn 22 dual-line
number 202
no forward local-calls
call-forward noan 200 timeout 30
!
The "forward local-calls" command is enabled by default. It can also be used in conjunction with Hunt Groups. More information on:
