Table A-45: Call Hold Parameters
Enables interworking of the Hold/Retrieve supplementary service from
PRI to SIP.

[0] Disable

[1] Enable (default)
Notes:

To support interworking of the Hold/Retrieve supplementary service
from SIP to ISDN (Euro ISDN), set the parameter EnableHold2ISDN to
1.

This parameter can also be configured per IP Profile, using the
IPProfile parameter (see 'Configuring IP Profiles' on page 236).
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).

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] = 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.
Determines whether the device sends DTMF signals (or DTMF SIP INFO
message) when a call is on hold.

[0] = Disable (default).

[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.
