the main proxy is not available. The keywords and

• tag: Number from 1 to 5 and the distinguishing factor
when there are multiple alias commands.
• pattern: The prefix number; matches the incoming
telephone number and may include wildcards.
• to: Connects the tag number pattern to the alternate
number.
• target: The target number; an alternate telephone
number to route incoming calls to match the number
pattern.
• preference value: (Optional) Assigns a dial-peer
preference value to the alias. The value argument is the
value of the associated dial peer, and the range is from
1 to 10. There is no default.
