© 2005 Cisco Systems, Inc. All rights reserved. IPTX v Ephone and Ephone-dn Concepts Ephone and ephone-dn have modular IOS software construction. Ephone represents the physical phone and is limited by license and hardware. Ephone-dn can be associated with one or more ephones. An ephone can have more than one ephone-dn associated with it. The maximum number of extensions is the same as the maximum number of ephone-dns.

© 2005 Cisco Systems, Inc. All rights reserved. IPTX v Ephone-dn Features DN1 Directory number and extension number are equivalent Line and voice port are equivalent Sequence number, or dn-tag, is unique (is assigned when the ephone-dn is created) Can have one or more telephone numbers associated with it Can have one or two voice channels When it is initially configured, it creates one or more telephony system POTS dial peers DN1 and DN2 Primary and secondary extensions configured on a single-line ephone-dn in which the primary is an internal extension number and the secondary is an E.164 number One phone extension on a dual-line ephone-dn for ephone-dns that need call waiting, consultative transfer, and conferencing DN1 Primary extension number on a single-line ephone-dn that can make or receive one call at a time Ephone-dn

© 2005 Cisco Systems, Inc. All rights reserved. IPTX v Single-Line Ephone-dn CMERouter(Config)#ephone-dn 1 CMERouter(Config-ephone-dn)#number One channel One virtual voice port The ephone-dn creates one virtual voice port. Only one call to or from this ephone-dn can occur at any one time.

© 2005 Cisco Systems, Inc. All rights reserved. IPTX v CMERouter(Config)#ephone-dn 2 dual-line CMERouter(Config-ephone-dn)#number 1002 The ephone-dn creates one virtual voice port. The dual-line keyword indicates two voice channels for calls to terminate on an ephone-dn extension. This should be used on ephone-dns that need call waiting, consultative transfer, and conferencing on one button. This cannot be used on ephone-dns that are used for intercoms, paging, MWI, call parking slots, and MOH feeds. Dual-Line Ephone-dn 1002 Two channels One virtual voice port

IPTX v Primary and Secondary Extension Number on One Ephone-dn CMERouter(Config)#ephone-dn 6 CMERouter(Config-ephone-dn)#number 1005 secondary no-reg primary 1005 and One channel One virtual voice port The ephone-dn creates one virtual voice port. Two different directory numbers can be dialed to reach this ephone-dn. One call connection is allowed if configured as a single-line ephone-dn. Two call connections are allowed if configured as a dual-line ephone-dn. This ephone-dn type allows two numbers to be configured without using an extra ephone-dn. The secondary number is registered to the H.323 gatekeeper or SIP proxy server.

© 2005 Cisco Systems, Inc. All rights reserved. IPTX v Shared Ephone-dn One ephone-dn is applied on two different ephones. Only one Phone can use the ephone-dn at a time. Both Phones ring when a call arrives at the ephone-dn. Only one ephone can pick up the call, ensuring privacy.

When the two voice channels on the ephone-dn are being used on line button 1, an incoming call rolls to the ephone-dn that is assigned to line button 2. A fifth call receives busy treatment when both voice channels on both ephone-dns are being used on line buttons 1 and 2. The preference of 0 is more preferred than the preference of 1; the default is 0. The no huntstop on the line button 1 ephone-dn allows the call to hunt to the second ephone-dn when the first ephone-dn is busy. The huntstop on the line button 2 ephone-dn stops the hunting behavior and applies the busy treatment. Ephone

When the first ephone-dn is being used on ephone 4, an incoming call uses the ephone-dn that is assigned to ephone 5. A third call receives busy treatment when both ephone-dns are being used on ephones 4 and 5. The preference of 0 is more preferred than the preference of 1; the default is 0. The no huntstop on the ephone-dn on ephone 4 allows the call to hunt to the second ephone-dn on ephone 5 when the first ephone-dn is busy. The huntstop on the ephone-dn on ephone 5 stops the hunting behavior and applies the busy treatment for the third call.

© 2005 Cisco Systems, Inc. All rights reserved. IPTX v Summary Ephone-dns and ephones are two key components in the Cisco CallManager Express system. An ephone-dn is a single instance of an extension (directory) number. An ephone is a single instance of the configuration of the physical instrument. There are different types of ephone-dns: –Single-line ephone-dn –Dual-line ephone-dn –Primary and secondary extension on one ephone-dn –Shared ephone-dn –Multiple ephone-dns on one ephone –Multiple ephone-dns on different ephones –Overlay ephone-dn
