Table 3-33: Supplementary Services Parameters

Parameter Description

Enable Hold

[EnableHold]

Allows users (connected to the device) to place a call on hold.

 [0] Disable = Disables the Hold service.

 [1] Enable = Enables the Hold service (default).

If the Hold service is enabled, a user can place the call on hold (or

remove from hold) using the hook-flash. On receiving a Hold request,

the remote party is placed on hold and hears the hold tone.

Note: To use this service, the devices at both ends must support this

option.

Hold Format

[HoldFormat]

Determines the format of the call hold request.

 [0] 0.0.0.0 = The connection IP address in SDP is 0.0.0.0 (default).

 [1] Send Only = The SDP contains the attribute 'a=sendonly'.

Held Timeout

[HeldTimeout]

Determines the time interval that the device can allow a call to remain

on hold. If a Resume (un-hold Re-INVITE) message is received before

the timer expires, the call is renewed. If this timer expires, the call is

released.

 [-1] = The call is placed on hold indefinitely until the initiator of on

hold retrieves the call again(default).

 [0 - 2400] =Time to wait in seconds, after which the call is released.

Call Hold Reminder Ring

Timeout

[CHRRTimeout]

Defines the timeout (in seconds) for applying the Call Hold Reminder

Ring. If a user hangs up while a call is still on hold, then the FXS

interface immediately rings the extension for the duration specified by

this parameter. If the user off-hooks the phone, the call becomes active.

The valid range is 0 to 600. The default value is 30.

Note: This parameter is applicable only to FXS interfaces.

Enable Transfer

[EnableTransfer]

Determines whether call transfer is enabled.

 [0] Disable = Disable the call transfer service.

 [1] Enable = Enable the call transfer service (using REFER)

(default).

If the transfer service is enabled, the user can activate Transfer using

hook-flash signaling. If this service is enabled, the remote party

performs the call transfer.

Notes:

 To use call transfer, the devices at both ends must support this

option.

 To use call transfer, set the parameter EnableHold to 1.

Transfer Prefix

[xferPrefix]

Defines the string that is added as a prefix to the transferred / forwarded

called number when the REFER / 3xx message is received.

Notes:

 The number manipulation rules apply to the user part of the REFER-

TO / Contact URI before it is sent in the INVITE message.

 This parameter can be used to apply different manipulation rules to

differentiate transferred / forwarded number from the originally dialed

number.
