Introduction

This document describes the most common Jabber Softphone for VDI issues and how to correct them.

Prerequisites

Requirements

Cisco recommends that you have knowledge of Cisco Unified Communications Manager (CUCM) and Jabber Softphone for VDI (JVDI).

Components Used

The information in this document is based on the listed software versions:

- Cisco Unified Communications Manager 14.0.1 SU2

- Cisco Jabber 14.1.3

- JVDI Agent 14.1.3

- JVDI Client 14.1.3

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Common Problems and Solutions

CTI Errors

If a JVDI softphone failure is due to a failed CTI connection, the Jabber connection status from the VDI displays the virtual channel and SIP as connected but CTI as Not Connected.

CTI Connection Failure

When the SIP connection from the JVDI Client is working and there is a CTI failure occurring, the Jabber CSF device displays as registered from the CUCM Administration > Device > Phone website.

CSF registered during CTI failure

CTI Timeout

To verify if a CTI timeout occured collect the listed traces and logs.

- CUCM CTIManager Traces

- Jabber Problem Report from virtual desktop infrastructure (VDI)

CUCM CTIManager SDL Trace show that CTIManager attempts a rebind to LDAP and sets the network timeout to 5 seconds.

CUCM CTIManager SDL Trace indicates that CTIManager verified the timeout period has passed and sends a provider complete event containing a timeout error to Jabber.

Jabber log shows Jabber received the PROVIDER_OPEN_COMPLETED_EVENT from CTIManager and closes the CTI connection due to the timeout error received.

CTI Timeout Solutions

1. Verify the CUCM LDAP Authentication port in use. Changing the authentication port to a Global Catalog port (3268\3269) can reduce delay for authentication requests.

2. Verify if LDAP Authentication servers are configured as fully qualified domain name (FQDN). If so, make sure all server FQDN are resolvable via DNS from CUCM.

Note: Cisco CTIManager does need to be restarted whenever the authentication port is changed.

CTI Permissions

To verify if CTI Permissions are the cause of a CTI failure collect the listed traces and logs.

- CUCM CTIManager Traces

- Jabber Problem Report from VDI

CUCM CTIManager SDL Traces show CTIManager verifying the user settings. During the settings verification CTIManager sends a ProviderOpenCompletedEvent notifying Jabber that the user does not have the correct permissions to perform CTI control.

CTI Permissions Solution

1. This issue can be solved by adding the Standard CTI Enabled role to the CUCM end users configuration (CUCM Administration > User Management > End User).

Standard CTI Enable CUCM end user role

CTI Line Control Disabled

To verify if CTI line control errors exist collect the listed traces and logs.

- CUCM CTIManager Traces

- Jabber Problem Report from VDI

CUCM CTIManager SDL Trace show CTI Manager received a LineOpenRequest from Jabber. CTIManager is unable to perform the line open and sends a line open failed event to Jabber.

Line Close Solution

Verify the Allow Control of Device from CTI setting is enabled on the CSF Line configuration (CUCM Administration > Device > Phone).

Directory Number CTI Permissions

Note: If the "Allow Control of Device from CTI" is enabled on the line but the CTI errors are still seen, toggle the setting off and on saving between changes.

CTI Device Association

To verify if CTI device association errors exist collect the listed traces and logs.

- CUCM CTIManager Traces

- Jabber Problem Report from VDI

CUCM CTIManager SDL Trace reveal CTI Manager receives the PROVIDER_OPEN_REQUEST and sends a provider response with user authentication successful.

CTI Device Association Solution

1. These errors are seen when the JVDI CSF devices is not present in the CUCM end user Controlled Devices. Adding the CSF device to the controlled devices to correct this issue (CUCM Administration > User Management > End User).

CUCM Controlled Devices

CTI Device Control Disabled

To verify if CTI device control is disabled.collect the listed traces and logs.

SIP Errors

When a JVDI softphone failure is due to a failed SIP connection, the Jabber connection status from the VDI displays the virtual channel as connected but the SIP and CTI status show as Not Connected.

JVDI SIP Error

When the SIP connection from the JVDI Client is failing the Jabber CSF device shows as unregistered from the CUCM Administration > Device > Phone website.

CUCM CSF Unregistered

SIP Socket Failure

With JVDI all SIP traffic originates from the JVDI Client on the thin client machine. To troubleshoot collect the listed traces and logs.

Common Solutions for SIP socket failures:

1. Verify if you are attempting to use JVDI over VPN or if your connecting to the VDI using Citrix Access Gateway or VMware Access Gateway.

- If a VPN is in use verify the JVDI required ports are allowed on all appropriate security appliances. Reference the Port Requirement section of the Jabber Softphone for VDI Deployment and Installation Guide.

- If you are using Citrix Access Gateway or VMware Access Gateway Cisco JVDI requires MRA to be used. Support for JVDI over MRA begins in JVDI and Jabber version 12.6.

2. If JVDI Client is experiencing this issue on a internal network verify:

- Routing between the Thin Client VLAN and the CUCM VLAN.

- Verify all required ports for JVDI are reachable. Reference the Port Requirement section of the Jabber Softphone for VDI Deployment and Installation Guide.

- Collect a Packet Capture from the Thin Client and the CUCM

- Verify if the TCP Syn is making it to the CUCM

- Verify if the thin client or server is resetting the TCP session.
