Cisco Mobile provides iPhone users with voice over IP (VoIP) calling,
visual voicemail, and access to the corporate directory while users are
connected to the corporate network over Wi-Fi, either on premises or over VPN.
Cisco Mobile is an IP telephony endpoint that is configured in Cisco
Unified Communications Manager (CallManager). It is distinct from the Cisco
Mobile application that runs in conjunction with a Cisco Unified Mobility
This document provides answers to frequently asked questions about
troubleshooting Cisco Mobile for Apple iPhone.
How can I make a Cisco Mobile Device available in Cisco Unified
A. When you add devices to Cisco Unified Communications Manager, it is
sometimes necessary to add a .cop file to the CUCM
database. This step is generally required for devices that are not natively
present in the Cisco Unified Communications Manager device list.
CUCM versions that require the .cop file include:
CUCM versions that do not require the .cop file include:
You can download the .cop file from
Cisco Unified Mobile Communicator - Download
registered customers only)
How can I make sure that the .cop file is supported by CUCM that is
iPhone compatiblity with CUCM?
A. A single device .cop file supports all Cisco Mobile 8.x releases.
However, not all Cisco Unified Communications Manager versions support Cisco
How do I register an iPhone on the Cisco Unified Communications Manager?
A. Complete these steps in order to register an iPhone on the Cisco
Unified Communications Manager:
If Cisco Dual Mode For iPhone does not exist under the phone type,
install the .cop file.
After you install the .cop file, reboot the CUCM server, and then
restart the Tomcat service from the CLI.
Choose DEVICES > ADD NEW > CISCO DUALMODE FOR
IPHONE, and add a new iPhone device.
Type TCT%USERNAME% for the name of the device (where
%USERNAME% is replaced with the user's user ID, which must be uppercase
Set the Device Security Profile to Cisco Dual Mode for iPhone –
Standard SIP Non-Secure Profile.
Optionally, if SIP digest authentication is desired, assign the SIP
DIGEST user name from the drop-down list.
Download the Cisco Mobile app from the Apple App
Open the application, and choose Enter Account Settings >
Choose Yes under User Integration in order to link
your iPhone and desk phone.
You are prompted for your CUCM end user login information. Make sure
that this end user is associated with both the iPhone and the desk phone.
I am unable to pull directory information with my iPhone. How do I
integrate corporate directory with a Cisco Mobile 8.X
A. In order to allow the Cisco Mobile client access to the corporate
directory, you must add support for Microsoft Active Directory.
By default, Cisco Mobile uses these two methods in order to identify
the corporate directory:
If you add support for Microsoft Active Directory, Cisco Mobile also
attempts to identify numbers using the corporate directory.
Cisco Mobile 8.0 does not complete outbound calls. The PSTN destination
rings only once and then disconnects. How do I resolve this
A. This issue can occur due to codec restrictions if Cisco Mobile is being
used over 3G, as described in the next question. One possible adjustment which
can help with codec negotiation on H.323 endpoints is disable the Wait for
Far-end h.245 gateway to send capabilities option, and enable the Fast Start
option on the Gateway configuration page of CUCM.
Why am I unable to make call to Auto Attendant with my iPhone? There is
no audio over the G.711u codec.
A. You cannot call the Auto Attendant, which supports only codec G.711.
Cisco Mobile 8.x supports both G.711 and G.729 when connected to Cisco Unified
Communications Manager via Wi-Fi but supports only G.729 when connected via 3G
(GSM). When the Low Bandwidth Codec option on Cisco Mobile is set to
ON, Cisco Mobile can use only G.729 and not G.711. In
order to resolve this issue, set the Low Bandwdith Codec option to
Off, connect via WiFi, or configure a hardware
What is the Email Provisioning Tool for Cisco
A. The Email Provisioning Tool allows administrators to send a
provisioning email to users, which facilitates installation and configuration
of Cisco Mobile. Users download Cisco Mobile from the App Store, open the email
created by this tool, and click a link contained in the email. Users are not
required to enter any settings other than possibly their password. The Email
Provisioning Tool is an open source tool, and it must be customized for use in
What is the difference between Cisco Mobile and Cisco Unified Mobile
A. Cisco Mobile is a dual-mode client and is primarily focused on
employees who have access to WLAN infrastructure, either at work or at various
remote sites. You need VPN on the iPhone to connect to the office when you use
Wi-Fi from a remote location, such as a public hotspot or home. Cisco Unified
Mobile Communicator 7.1 provides VPN-less remote access to Cisco Unified
Communications Manager and, therefore, is best used for workers who spend most
of their time away from the office and on other reliable data networks.
