Table 51-47: Call Hold Parameters
Global parameter that enables the interworking of the Hold/Retrieve
supplementary service from ISDN PRI to SIP. You can also configure this
functionality per specific calls, using IP Profiles (IpProfile_EnableHold).
For a detailed description of this parameter and for configuring this
functionality in the IP Profile table, see ''Configuring IP Profiles'' on page
329.
Note: If this functionality is configured for a specific IP Profile, the settings
of this global parameter is ignored for calls associated with the IP Profile.
Defines the format of the SDP in the sent 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.
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.
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.
