ISR SMS Authorization (White List): Regular Expression Examples

The commandsoversms applet offers optional security by limiting who can execute
commands via text message on the ISR.  The feature is enabled by defining an EEM variable
called “whitelist”.   The variable’s value is a regular expression that can represent one or
more phone numbers, either by defining multiple numbers, or patterns for numbers.  Below
are a few examples.

Match single phone number:

event manager environment whitelist 2125550101

Match any three phone numbers:

event manager environment whitelist (2195550202|5495550168|6195556035)

Match 3 area codes followed by any number:

event manager environment whitelist (212|540|610)[0-9]+

Match 2 area codes associated with specific prefixes followed by any number:

event manager environment whitelist (212555|540555)[0-9]+
