Parameter Description
Web/EMS: Hold Format
[HoldFormat]
Determines the format of the SDP in the Re-INVITE hold request.

[0] 0.0.0.0 = (Default) The SDP "c=" field contains the IP address
"0.0.0.0" and the "a=inactive" attribute.

[1] Send Only = The SDP "c=" field contains the device's IP address
and the "a=sendonly" attribute.

[2] x.y.z.t = The SDP "c=" field contains the device's IP address and
the "a=inactive" attribute.
Notes:

The device does not send any RTP packets when it is in hold state.

This parameter is applicable only to QSIG and Euro ISDN protocols.
Web/EMS:Held Timeout
[HeldTimeout]
Defines the time interval that the device allows for 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
(terminated).

[-1] = (Default) The call is placed on hold indefinitely until the initiator
of the on hold retrieves the call again.

[0 - 2400] = Time to wait (in seconds) after which the call is released.
[PlayDTMFduringHold]
Determines whether the device sends DTMF signals (or DTMF SIP INFO
message) when a call is on hold.

[0] = (Default) Disable.

[1] = Enable - If the call is on hold, the device stops playing the Held
tone (if it is played) and sends DTMF:

To Tel side: plays DTMF digits according to the received SIP
INFO message(s). (The stopped held tone is not played again.)

To IP side: sends DTMF SIP INFO messages to an IP destination
if it detects DTMF digits from the Tel side.
53.11.5.5 Call Transfer Parameters
The call transfer parameters are described in the table below.
Call Transfer Parameters
Parameter Description
Web/EMS: Enable
Transfer
[EnableTransfer]
Enables the Call Transfer feature.

[0] Disable

[1] Enable = (Default) The device responds to a REFER message
with the Referred-To header to initiate a 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.
Web: Transfer Prefix
EMS: Logical Prefix For
Transferred Call
[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
and/or Contact URI before it is sent in the INVITE message.

This parameter can be used to apply different manipulation rules to
differentiate transferred number from the originally dialed number.
