Placing a Call On Hold

The accepted incoming or outgoing voice call can be placed On Hold. To place the call On Hold, click Line button. Note that selecting another line also puts an existing call On Hold without hanging up.

When the call is On Hold, the Call On Hold message is displayed in the Info panel and the line is flashing yellow.

To resume a call, click the line that is On Hold.

You can configure Fax Voip Softphone so that the caller who is put on hold listens to Music On Hold while waiting on the phone. To configure Music On Hold, click Settings in the main toolbar, in the Fax Voip SoftPhone Control Panel click Play/Record in the treeview. Tick Play music when On Hold option and browse to a preferred Music On Hold File. A Music On Hold File must be an 8 kHz 16-bit Mono or 8 kHz 8-bit Mono wave file (.wav). In the Fax Voip SoftPhone Control Panel click Apply to save settings. See also in the Call Recording and Playback Settings chapter of this manual. To create the audio file that is suitable for using as Music On Hold File, you can use the procedure described in the Send an audio message with Create Audio Message Wizard chapter of this user manual. To save the audio file somewhere on your hard drive, use the Save as... button in the Create Audio Message Wizard.

If the call is On Hold and the Music On Hold is played, the PLAY indicator is displayed in the Info panel.

Notes

• You are not able to place the outgoing call On Hold if the call is in dialing stage (Trying or Ringing).
• You are not able to place the active call On Hold at the time of playing of the audio file (after manual clicking Play button). This restriction does not apply to the case in which the audio message is sent with dialing number.
• Please note that the Call On Hold function in the Fax Voip Softphone is currently implemented in the emulation mode. This means that the softphone does not send any SIP or H.323 messages (a=sendonly, a=sendrecv etc.) that inform the phone network that the call is On Hold. On the one hand, this does not allow to use of some functions of VOIP servers, such as playing of Music On Hold on the side of VOIP server. But on the other hand, this implementation solves the incompatibility issues with different SIP and H.323 systems. Keep in mind, that the Music On Hold function is realized internally and does not depend on the capabilities of your SIP or H.323 server.
• If the other party of the call is On Hold, the Remote On Hold message is displayed in the Info panel.
