Example: Using Digit Manipulation Tools

The following is a sample configuration using the prefix command:

dial-peer voice 1 pots

destination-pattern 555....

prefix 555

port 1/0/0

In the sample configuration using the prefix command, the device attached to port 1/0/0 needs

all seven digits to process the call. On a POTS dial peer, only wildcard-matched digits are

forwarded by default. Use the prefix command to send the prefix numbers 555 before

forwarding the four wildcard-matched digits.

The following is a sample configuration using the forward-digits command:

dial-peer voice 1 pots

destination-pattern 555....

forward-digits 7

port 1/0/0

In the sample configuration using the forward-digits command, the device attached to port

1/0/0 needs all seven digits to process the call. On a POTS dial peer, only wildcard-matched

digits are forwarded by default. The forward-digits command allows the user to specify the

total number of digits to forward.

The following is a sample configuration using the number expansion table (num-exp)

command:

num-exp 2... 5552...

dial-peer voice 1 pots

destination-pattern 5552...

port 1/1/0

In the sample configuration using the num-exp command, the extension number 2… is

expanded to 5552… before an outbound dial peer is matched; for example, the user dials 2401,

but the outbound dial peer 1 is configured to match 5552401.

The following is a sample configuration using the digit translation (translation-rule)

command:

translation-rule 5

rule 1 2401 5552401

dial-peer voice 1 pots

translate-outgoing called-number 5

In the sample configuration using the translation-rule command, the rule is defined to

translate 2401 into 5552401. The dial peer translate-outgoing called-number 5 command

notifies the router to use the globally defined translation rule 5 to translate the number before

sending the string out the port. It is applied as an outbound translation from the POTS dial peer.
