required.
Selects the Bellcore VMWI sub-standard.
[0] = Between rings (default).
[1] = Not ring related.
Note: For this parameter to take effect, a device reset is
required.
Table 12-42: Call Hold Parameters
For digital interfaces:
[0] Disable
[1] Enable (default)
If the Hold service is enabled, a user can place the call on hold (or
remove from hold) using the Hook Flash button. On receiving a Hold
request, the remote party is placed on hold and hears the hold tone.
Notes:
For digital interfaces: To support interworking of the Hold/Retrieve
supplementary service from SIP to ISDN (for QSIG and Euro ISDN),
set the parameter EnableHold2ISDN to 1.
For analog interfaces: To use this service, the devices at both ends
must support this option.
This parameter can also be configured per IP Profile, using the
IPProfile parameter (see ''Configuring IP Profiles'' on page 143).
Determines the format of the SDP in the Re-INVITE hold request.
[0] 0.0.0.0 = The SDP "c=" field contains the IP address "0.0.0.0" and
the "a=inactive" attribute (default).
[1] Send Only = The SDP "c=" field contains the device's IP address
and the "a=sendonly" attribute.
Notes:
The device does not send any RTP packets when it is in hold state (for
both hold formats).
For digital interfaces: This parameter is applicable only to QSIG and
Euro ISDN protocols.
Determines 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] = The call is placed on hold indefinitely until the initiator of the on
hold retrieves the call again (default).
[0 - 2400] = Time to wait (in seconds) after which the call is released.
