ISDN interface configuration task list 395
SmartWare Software Configuration Guide 34 • ISDN interface configuration
Sending the connected party number (COLP) (optional)
Sending the connected party number (COLP) can be suppressed by the command send-connected- party-num-
ber.
Mode: context cs/interface isdn
Enabling sending of date and time on ISDN DSS1 network interfaces
This procedure enables sending of date and time information on an ISDN network side interface.
Mode: interface isdn <if-name>
Defining the ‘network-type’ in ISDN interfaces
The following command defines the location code to be inserted in ISDN causes code information elements.
Mode: interface isdn <if-isdn>
ISDN Explicit Call Transfer support (& SIP REFER Transmission)
Additional call transfer support is enabled by default for ISDN interfaces (BRI ports) by accepting or rejecting
explicit call-transfer (ECT) invocations. An ISDN phone that is connected to a BRI port and that has two
active calls can send an ECT invocation to connect the two calls inside the device. An ISDN interface can be
configured to accept or reject ECT invocations.
SmartWare detects calls that are looped internally, i.e. calls that leave the device over the same ISDN interface
over which they enter the device. If an internal loop is detected for an ISDN interface bound by an ISDN user
port, SmartWare sends an explicit call-transfer (ECT) to push back the call to the connected network as soon
as the call is connected. An ISDN interface can be configured to emit ECT invocations.
SIP interfaces react similarly to internally looped calls. If a call leaves the device over the same SIP gateway over
which it entered the device, SmartWare sends a REFER message to one of the remote user agents to transfer
the call to the two parties. A SIP interface can be configured to emit REFER messages.
Figure 56 shows an example scenario where a SIP network connects two devices to give a home office (HO)
access to a PBX in the central office (CO).
