Command Reference Guide
ip sip proxy failover match-alias <pattern> substitute <pattern>
Use the ip sip proxy failover match-alias substitute command to configure an alias to match a dial string
and substitute the specified pattern. This feature is used to route a survivability call when the Session
Initiation Protocol (SIP) proxy is in failover mode. If an INVITE message is directed toward a matching
alias, the substitution pattern is evaluated and compared to current proxy users. The first user to match the
substitution pattern is selected to receive the SIP message. Use the no form of this command to return to
the default setting.
Syntax Description

Default Values
By default, there are not match-alias substitutions defined.
Command History
Release A4.05
Functional Notes
SIP proxy failover occurs using an automatically created trunk contained in AOS's basic configuration. This
trunk is a hidden SIP trunk with the same default settings as a regular SIP trunk. For more information
about configuring SIP proxy failover, refer to the Configuring SIP Proxy in AOS configuration guide
available online at https://supportforums.adtran.com
Both the match-alias <pattern> and the substitute <pattern> parameters can be defined using traditional
number matching and regular expression matching methods. Traditional number matching uses numbers
and wildcard variables to enter a pattern. Available characters are as follows:
0-9 = Match exact digit only.
M = Any digit 1 to 8.
X = Any single digit 0 to 9.
N = Any digit 2 to 9.
[123] = Any digit contained in the bracketed list.
Do not use dashes, commas, spaces, etc., inside the brackets. Commas are implied
between numbers in the brackets.
