A business phone system is expected to provide the following features:

•

Music on Hold

•

Call Forward

•

Call Transfer

•

Call Park

•

Intercom

•

Call Pickup

•

Call Blocking

•

The next sections describe the configuration of these basic business telephony features in CM Express.

Directory Services

Music on Hold

No one likes to be on hold, but having something to listen to makes it a little better and can even relay useful information

to the listener. Configuring Music on Hold (MOH) in CM Express is simple. First copy a .wav file to Flash (avoiding

copyright issues by using royalty-free recordings). Next, issue the command

mode. By default, the router will multicast the stream to 239.23.4.10:2000; if you need to change this default multicast

address (typically you do not), issue the command

moh wavefilename.wav in config-telephonymulticast moh ip-address port port-number.

Call Forward

The user can configure call-forwarding of all calls using the phone softkey. Using the CLI, you can configure different

call-forwarding options at the config-ephone-dn prompt:

•

call-forward all directory-number: Forwards all calls to the specified directory number.

•

call-forward busy directory-number: Forwards calls to the specified number if the user is on the phone.

•

does not answer the phone before the specified timeout.

call-forward noan directory-number timeout seconds: Forwards calls to the specified directory number if the user

•

prevents call forwarding to an international long-distance number, for example.

call-forward maxlength length: Restricts the number of digits specified for the call-forwarding number; this

Call Transfer

Users can transfer calls with the Transfer softkey; the administrator can configure how this transfer happens using the

transfer-system {blind I full-blind I full-consult llocal-consult}

as follows:

config-telephony command. The command options are

•

Blind: Calls are transferred immediately using a Cisco-proprietary method.

• Full-blind:

Calls are transferred immediately using the H.450.2 standard.

•

the call is released); uses the H.450.2 standard.

Full-consult: Calls are transferred with consultation (meaning the user must speak to the target of the transfer before

•

Local-consult: Uses a proprietary transfer method; not commonly used.

Call Park

Call park allows a user to hold a call but retrieve it from another location by dialing the call park extension. A call-park

extension is a "floating" ephone-dn that is not assigned to any ephone. Multiple calls can be parked at a single extension

and are retrieved by dialling the extension; calls are picked up in the order in which they were parked. The syntax is relatively

complex and specifies several options:

•

[transfer

park-slot [reserved-for extension-number] [timeout seconds limit count] [notify extension-number [only]] [recall]extension-number][alternate extension-number][retry seconds limit count].

• reserved-for:

number as its primary line. All lines on that phone can use this park slot.

(Optional) Indicates that this slot is a private park slot for the phone with the specified extension

•

When the interval expires, the Call Park reminder sends a 1-second ring and displays a message on the LCD panel of

the Cisco IP Phone that parked the call and to any extension that is specified with the

The following example creates four call-park slots. Ephone-dn 10 and 11 can be used by any extension. A call parked in

these slots will stay parked for 100 seconds and will send a notification every 10 seconds to the extension that parked it.

If the 100-second limit elapses, the parked call is automatically transferred to 5309; if 5309 is busy or does not answer, it

goes to 5310. Ephone-dn 12 and 13 are reserved for 5301 and 5302, respectively. After a call has been parked for 100

seconds, it will be disconnected.

seconds: (Optional) Sets the delay before another attempt to recall or transfer a parked call, in seconds. Thelimit keyword.

Intercom

An intercom is a one-way audio speed-dial. Commonly used by an executive to an admin assistant, it allows the user to

press a phone button and be directly connected to another user. The destination phone answers the call in muted speakerphone

mode so that privacy is maintained. Any user could dial the intercom if the extension is known. To make it impossible

for anyone to dial the intercom (except those phones configured to do so), the extension number of the intercom can

include the A, B, C, or D character. These characters were at one time part of the touchtone dialpad,

no longer on the phone itself, users cannot dial them; it is still possible to configure them in an ephone-dn, however. The

following configuration shows a typical intercom configuration, using the B digit as part of the intercom extension

Paging

Audio paging builds a one-way audio path from the speaker to a single phone, a group of phones, or combined groups of

phones. A paging group is created by configuring a dummy ephone-dn with the

ephone-dn with one or more ephones using the

phones answer the call in muted speakerphone mode. The default transport is unicast, which limits paging to a

maximum of 10 targets; multicast is also supported. The command syntax to create the ephone-dn is the following:

paging command and associating thatpaging-dn command. When a user dials the paging extension, all configured

Router(config-ephone-dn)# paging [ip

multicast-address port udp-port]

The following shows the syntax for associating an ephone to the paging ephone-dn. Note the

override the multicast configuration if the phone is not reachable by multicast:

unicast keyword, which will

Router(config-ephone)# paging-dn

The following example sets up a single paging group:

emergency use, or simply to combine other groups for paging.

the leading characters must be unique to each group; for example, the group numbers 81 and 817 will both be interpreted

If the ringing extension is in the user's group, pressing the Pickup softkey will redirect the call to the user's phone. If the

ringing extension is in another group, the user must press the GPickup softkey and enter the group number of the ringing

extension.

Local group pickup: Users can pick up a ringing extension in their own group using the Pickup softkey plus thepickup-group number. The numbers are arbitrary, but

Call Blocking

Call blocking prevents unauthorized use of phones, typically to specific number patterns or times of day. You can define

up to 32 patterns of digits to block and apply a time schedule to restrict calls to whatever schedule suits your needs. Call

blocking applies to all IP Phones (except analog FXS phones), but phones can be exempted from call blocking individually.

An override function exists, configurable with a PIN for authorized users.

The schedule can be configured by day or by date using the following config-telephony commands:

a f t e r - h o u r s day day s t a r t - t i m e stop-time

a f t e r - h o u r s date month date s t a r t - t i m e stop-time

When the after-hours schedule is in place, use the

block command to activate call blocking:

a f t e r - h o u r s block pattern tag

pattern [7-24]

The patterns use the same syntax as dial plan patterns. Using the

day,

The following configuration sets up a call blocking plan for all calls outside of normal business hours of 8:00 a.m. to 5:00

p.m., Monday through Sunday, and the holidays for New Year's day, the Fourth of July, and Christmas day:

7-24 keyword blocks the configured pattern 24 hours a7 days a week, and disables the override PIN functionality.

Exempting a phone from after-hours blocking is easily configured with the

prompt. Adding a PIN is equally simple at the same prompt with

after-hours exempt command at the configephonepin pin-number.

Directory Services

Users can access the list of numbers and names by pressing the Directory key. Directory entries are drawn from the

ephone-dn configuration if it includes a

with the name being up to 24 characters. The directory entries can be listed as first-name-first or last-name-first;

whichever method is chosen, the name under the ephone-dn configuration should match to avoid confusion. The configtelephony

command to specify how names in the directory shall be displayed is the following:

name entry. CM Express supports 100 directory entries of up to 32 characters,

d i r e c t o r y { f i r s t - n a m e - f i r s t

| l a s t - n a m e - f i r s t}

It is possible to configure a directory entry that is not an IP Phone. To create such an entry, use the following configtelephony

command:

d i r e c t o r y entry { [ e n t r y - t a g number name name] | c l e a r}
