does not support overlap sending). If disabled the keystrokes are immediately sent
to the IP-PBX.
10 To enable "DTMF through RTP Channel", select the DTMF through RTP channel
check box.
If enabled, DTMF digits are sent as RTP payload directly to the other endpoint. If
disabled, the DTMF is sent in the signalling channel.
11 If you in step 2 selected "SIP" protocol, enable or disable the following options in
the SIP Interoperability Settings section:
Registration time-to-live
This is the Expires-header in the REGISTER message. The default is 120 seconds.
To enable this option, enter a value specified in seconds in the "Registration time-
to-live" field.
If the system has many users (more than 1000), it is recommended to set the time-
to-live value to 600 seconds for IPBLs to avoid system overload.
Hold Signalling
Some IP-PBXs require special way of hold signalling. In the "Hold Signalling" list
field, select one of the following:
inactive: No media stream is sent or received.
sendonly: Media stream is sent only and not received.
sendonly with 0.0.0.0: Special case of sendonly where also the media IP address is
set to 0.0.0.0.
Hold before Transfer
If this option is enabled, the consultation call is put on hold before transfer. Some
IP-PBXs require this option so that both called parties are put on hold before the
transfer is carried out.
To enable this option, select the "Hold before Transfer" check box.
Accept Inbound Calls not Routed via Home Proxy
If this option is enabled it could be possible for inbound calls to bypass call
restrictions configured in the IP-PBX. If it is disabled a 305 Use Proxy response will
be sent.
To enable this option, select the "Accept inbound calls not routed via home proxy"
check box.
Register with number
If this option is enabled, number will be used for registrations towards the IP-PBX
instead of name. Name will be used for authentication.
To enable this option, select the "Register with number" check box.
12 Click "OK".
13 Reset in order to make the changes take effect, see 8.16 Reset on page 113.
8.5.16 Registration for Anonymous Devices
Portable Devices registered anonymously can make emergency calls through an extension
reserved for anonymous users.
Note: Call restrictions must be configured in the PBX to allow for emergency calls only.
This option also provides a solution for the case when the Master, running on an IPBS with
local power or an IPBL, loses IP connectivity without the local host Radio losing its
connection to the Master. The Portable Devices locked to this Radio become isolated from
the system without any notification.
