Cisco Cisco IOS Software Release 12.4(4)T

To assign an X.121 address to a rotary group (and optionally, to specify that address to be the source 
address of calls originating from lines within the group), use the x25 rotary command in global 
configuration mode. To remove an X.121 address from a rotary group, use the no form of this command.

x25 rotary group-num x121-address [calling-address [rotary | line]

no x25 rotary group-num x121-address [calling-address [rotary | line]

No group X.121 address is defined.

Global configuration

Each X.121 address can be associated with only one rotary group.

A rotary group cannot be configured with an X.121 address if it has “queued” or “queued-by-role” 
selection type.

The following example sets the rotary address to be used as the calling address:

Router(config)# x25 rotary 1 1111 calling-address rotary

A number from 1 through 127, assigned to identify the rotary group.

x121-address 

X.121 address. The address must be a numerical string no longer than 20 
digits.

calling-address (Optional) The source address of outgoing calls from members of this 

group. The default calling address is each line’s X.121 address.

Makes the rotary’s X.121 address the source address of outgoing calls.

Uses each line’s absolute address as the source address of outgoing calls.

12.4(4)T

This command was integrated into Cisco IOS 12.4(4)T.

Defines a group of lines as a rotary (“hunt”) group, and optionally, 
configures their response to connection requests.
