pickup 8005550100
When a DID incoming call to 800 555-0100 is received, the alias command routes the call at random to
one of the four extensions (5001 to 5004). Because the pickup command is configured, if the DID call
rings on extension 5002, the call can be answered from any of the other extensions (5001, 5003, 5004)
by pressing the PickUp soft key.
The pickup command works by finding a match based on the incoming DID called number. In this
example, a call from extension 5004 to extension 5001 (an internal call) does not activate the pickup
command because the called number (5001) does not match the configured pickup number (800
555-0100). Thus, the pickup command distinguishes between internal and external calls if multiple calls
are ringing simultaneously.
Configuring Global Prefixes
The dialplan-pattern command creates a dial-plan pattern that specifies a global prefix for the
expansion of abbreviated extension numbers into fully qualified E.164 numbers.
The extension-pattern keyword allows additional manipulation of abbreviated extension-number prefix
digits. When this keyword and its argument are used, the leading digits of an extension pattern are
stripped and replaced by the corresponding leading digits of the dial-plan pattern. This command can be
used to avoid Direct Inward Dialing (DID) numbers like 408 555-0101 resulting in 4-digit extensions
such as 0101.
Global prefixes are set with the dialplan-pattern command. Up to five dial-plan patterns can be created.
The no-reg keyword provides dialing flexibility and prevents the E.164 numbers in the dial peer from
registering to the gatekeeper. You have the option not to register numbers to the gatekeeper so that those
numbers can be used for other telephony services.
