Table 3-37: Supplementary Services Parameters
Parameter Description
Enable Hold
[EnableHold]
Enables interworking of the Hold/Retrieve supplementary service from PRI
to SIP.
 [0] Disable = Disables.
 [1] Enable = Enables (default).
For Mediant 1000 analog: 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.
Notes:
 This capability is only supported by the Euro ISDN variant and only from
TE (user) to NT (network).
 To support interworking of the Hold/Retrieve supplementary service
from SIP to ISDN, set EnableHold2ISDN to 1.
 To use this service, the Mediant analog 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'.
Note: This parameter is applicable only to QSIG and Euro ISDN protocols.
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 Mediant 1000 FXS interfaces.
Enable Transfer
[EnableTransfer]
Determines whether call transfer is enabled.
 [0] Disable = Disable the call transfer service.
 [1] Enable = (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. (Applicable only to Mediant 1000 analog interfaces.)
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 (only Mediant 1000 analog) number
from the originally dialed number.
