Cisco Collaboration 101-5: CUCM Mobile Connect (a.k.a CUCM Single Number Reach) configuration, make your deskphone and your Mobile (Cell) phone to ring at the same time


1. Configure Cisco Mobile Connect feature on a user phone

2. Any incoming calls to the user’s deskphone should ring simultaneously on the user deskphone as well as on his Mobile phone (0 + 0414024726) <<<This is an Australian mobile, just an example

3. Mobility softkey should be displayed on the user phone during the call and on-hook status

Step 1: Create a user on CUCM

Go to ‘User Management’ >’ End User’ > ‘Add New’

*If you already have an LDAP integration, simply use existing user and modify the settings for Cisco Mobile Connect

*Presuming that a user is an existing user with an IP Phone configured.

*The CUCM version used is version 10.5

Create a new user

Associate the user’s phone

Tick ‘Enable Mobility’ & ‘Enable Mobile Voice Access’

Click on ‘Save’ to save the changes

Step 2: Go to the user’s device (phone)

Go to ‘Device’ > ‘Phone’

Find the user’s phone

On Device settings, update the ‘Owner User ID’ filed with the user’s profile

Click on ‘Save’ to save the changes

On the same page, under ‘Related Links’, select ‘Copy to Remote Destination Profile’ and click on ‘GO’ button

Configure ‘Remote Destination Profile’, confirm that the information in the red boxes are correctly configured for your CUCM environment. Then click on ‘Save’ to save the changes

Under ‘Associated Remote Destinations”, click on ‘Add a New Remote Destination’

Configure ‘Remote Destination Configuration’, make sure that you place the leading ‘9’ or ‘0’ for calls going out. If the destination is an external number, then you MUST place the outgoing leading ‘9’ or ‘0’. If this is for an internal number, you can simply enter an internal extension.

*Note on above setup, the deskphone will ring for first 4 seconds, then followed by the ringing of the user’s mobile (cell) phone. Adjust the settings per client’s request.

Check ‘Line Association’ box and click on ‘Save’ button.

Go to ‘Device’ > ‘Device Settings’ > ‘Remote Destination Profile’

Click on the user’s extension

On the line settings, scroll down all the way, until you find ‘Multiple Call/Call Waiting Settins on Device rdp_mobile_brchoi and change the “Maximum Number of Calls’ from 2 to 1. Click on ‘Save’ button.

Step 3: Make a softkey for the phone

Go to ‘Device’ > ‘Device Settings’ > ‘Softkey Template’

Locate ‘Standard User’ softkey and copy

Rename it as ‘Standard User-Mobility’ and then, on ‘Related Links’, select ‘Configure Softkey Layout’ and click on ‘Go’ button.

Select when the phone is ‘On-Hook’, add ‘Mobility’ key and place the key as you like.

Select ‘Connected’ option, add ‘Mobility’ softkey and move it up or down as you like. Don’t forget to click on the Save button.

Go to ‘Device’ > ‘Phone’

Locate the same user phone and update the ‘Softkey Template’ to the template which has been created in previous task.

Don’t forget to click on the ‘Save’ button

Click on ‘Apply Config’

Click on ‘Reset’ button to make the change take place on the phone.


  • Make a call to the user’s deskphone extension, the phone will ring for 4 seconds, then the user’s Mobile/Cell phone will start ring.
  • As soon as the call is answered on either the deskphone or Mobile/Cell phone, the other phone will start ringing. Now you have a single number reach on this user’s phone.

Cisco Collaboration 101-2: CDP vs LLDP

CDP  (Cisco Discovery Protocol)

– Operates at L2

– Main function is to communicate and discover Cisco proprietary network devices

– CDP/CDPv2 is used for Cisco IP phone provisioning with VLAN and Quality of Service (QoS), power information.

– CDP/CDPv2 could be a security threat and in some network, it is recommended CDP is disabled, since it provides device information, such as the device names and IP addresses in VLAN 1.  A hacker can discovery device information carried by CDP.

– CDP is enabled on all Cisco Switch ports by default


LLDP (Link Layer Discovery Protocol)

– Operates at L2

– Main function is to communicate and discover vendor neutral (industry standard) network devices

– LLDP is not enabled and can be enabled by using the global ‘lldp run’ command


Show command examples:

sw3560e-1#show cdp neighbors


sw3560e-1#show lldp neighbors


sw3560e-1#show cdp interface gigabitEthernet0/5
GigabitEthernet0/5 is up, line protocol is up
Encapsulation ARPA
Sending CDP packets every 60 seconds
Holdtime is 180 seconds

sw3560e-1#show lldp interface gigabitEthernet 0/5

Tx: enabled
Rx: enabled
Tx state: IDLE

sw3560e-1#show lldp interface gigabitEthernet 0/40

Tx: enabled
Rx: enabled
Tx state: IDLE

sw3560e-1#show power inline
