You are the administrator for your company’s UCM network. Examine the exhibit below, and answer the
question:
The user named Joe Cambers is not able to use Cisco Jabber’s voice mail functionality.
Which of the following is most likely the reason?
A.
The softphone has no SIP profile.
B.
The softphone’s profile does not allow CTI control.
C.
The SIP trunk to the CUPS server is down.
D.
The Cisco Unity Connection server either is down or is not installed.
E.
The Cisco Jabber client is configured to require a nonexistent desk phone.
Explanation:
Most likely, the reason the user named Joe Cambers is not able to use Cisco Jabber’s voice mail functionality is
because the Cisco Unity Connection server either is down or is not installed. Cisco Unity Connection is a voice
mail platform that integrates with a Cisco Unified Communications Manager (UCM) system. The Cisco Jabber
client connects to Cisco Unity Connection by using a Representational State Transfer (REST) interface.
You can display and verify the backend systems to which the Cisco Jabber client is connected by clicking the
gear icon and Show Connection Status in the Cisco Jabber home window. Clicking Show Connection Status
displays the Connection Status window, which provides the connectivity status of every service to which Jabber
is connected or is configured to connect. Services that are preceded by a green check mark have connected
successfully. Services that display Not Connected or a caution icon have not connected successfully.
Although the user cannot use Cisco Jabber’s IM and Presence functionality in this scenario, it is because the
Session Initiation Protocol (SIP) trunk from UCM to the Cisco Unified Presence (CUPS) server either is down or
is not installed. Cisco Jabber relies on CUPS and the Extensible Messaging and Presence Protocol (XMPP) for
instant messaging (IM) and Presence functionality. Cisco Unity Connection is not required for IM and Presence
functionality.
The softphone has a SIP profile. Based on the value displayed in the SIP Profile field of the UCM Administration
page in this scenario, you can determine that the softphone is configured to use the Standard SIP Profile, which
is the default UCM SIP profile.
The softphone’s profile does allow Computer Telephony Integration (CTI) control. Based on the value displayed
in the Allow Control of Device from CTI field, you can determine that CTI control has been enabled for the
softphone. However, disabling this option would not disable Jabber’s IM functionality. CTI enables the Cisco
Jabber client to control aspects of a connected hardware phone, or desk phone. However, the Cisco Jabber
client does not require a desk phone. Both Jabber and Cisco Unified Personal Communicator communicate
with a desk phone by using the CTI Quick Buffer Encoding (CTIQBE) protocol.Cisco: Feature Comparison Cisco Messaging Products (Unity Express, Unity Connection, Unity)
