Workcloud Communication Voice Client 9x

Configuring the WebEx PBX

Zebra Voice Client now supports WebEx PBX, which requires secure transfer of audio packet communication. For securing audio packets, we are using a standard third-party library libsrtp.

Register WebEx

WebEx PBX can be registered in Zebra Voice Client by the following methods:

Users can register in WebEx by giving the valid extension parameters in the

Extension Manager

portal and use the same extension in voice using the shared profile URI.

Manually, the user can select WebEx PBX type in

Settings

Connection Parameters

PBX type

, and provide proper config details.

Add the mandatory Line address parameter, using which we can make SIP calls, and this parameter can be configured in

Settings

Connection Parameters

PBX type

.

Since Webex supports strings as user/sip id does not send line number, we have added a Line Number parameter in

Settings

Connection Parameters

PBX Type

.

If the line number is empty, it displays the user ID from WebEx.

Basic Call

Users can perform Basic one-to-one calls.

Users can select codecs.

Users can hold/resume calls at any point in time.

Users can perform long-duration calls.

WebEx call is supported only if SRTP is enabled. In stand-alone mode, at the time of registration, we do not receive caller ID unless we receive the call; hence, we are not showing it in the dashboard.

Do Not Disturb

Users can put the device in DND mode by clicking the DND button on the dashboard.

Call Forward

Users can configure

Call Forward

and provide an extension number to which the call has to be forwarded. Users can configure Call Forward by clicking the

Call Forward

button.

Call Transfer

Users can perform the call transfers by clicking the

Call Transfer

button, the call transfer types are as follows:

Consult First

- Speak to the new user before transferring.

Transfer Now

- Transfer without speaking to the new user.

If the user selects

Transfer Now

and the transferred call is sent to the destination device. If the destination device is in another call or busy, it plays a busy tone for a few seconds, and the

Transfer Call

is rejected.

Call History

Users can see their call history in the history tab.

Call Park/Unpark

The user can park an ongoing call by clicking the

Call Park

button available in the IN-CALL view.

Once you click the

Park

button, it plays a pre-defined recording, "Your call has been parked," and the call gets disconnected. You can also configure a call recall timer. If nobody unparks the call, the user receives a call back after the configured time.

Multiple Call Appearance

Users can receive multiple calls at a time and select any call to attend.
