Isdn Advice Of Charge Support - Patton electronics SmartNode Series Software Configuration Manual

SmartWare Software Configuration Guide
The push-back mechanism can be configured on each interface separately. Per default push-back is enabled for
ISDN and SIP interfaces. You only have to change the configuration if you don't want internally looped calls to
be pushed back to the network. The configuration command [no] call-transfer accept configures if an incom-
ing call-transfer request (e.g. ECT or REFER) shall be accepted. The configuration command [no] call-
transfer emit configures if a call reaching the device over this interface and leaving the device over this interface
shall be pushed back to the network, i.e. if a call-transfer request (ECT or REFER) shall be sent.
The following procedure disables the push-back mechanism on the ISDN interface connected to the PBX. No
ECT invocation is sent when a call is detected that is looped internally.
Step
1
node(ctx-ip)[ctx-name]# interface isdn
<if-name>
2
node(if-isdn)[if-name]# no call-transfer
emit
The following procedure disables the push-back mechanism on a SIP interface. No REFER message is sent
when a call is detected that is looped internally.
Step
1
node(ctx-ip)[ctx-name]# interface sip
<if-name>
2
node(if-sip)[if-name]# no call-transfer
emit

ISDN Advice of Charge support

The exchange of "Advice of Charge" information is supported between two ISDN interfaces. The charge infor-
mation can be transmitted and received over H.323. (See Chapter 38,
page 426 for additional information on AOC-D support for H.323). Without configuration changes Smart-
Ware tunnels the "Advice of Charge" information from an ISDN user interface to an ISDN network interface.
However you can disable AOC-S, AOC-D or AOC-E separately on each interface.
The network sends tariff information about a call using AOC-S messages at call (S)etup time and during the
call when the tariff changes. Then (D)uring the call, the network sends the current charge in AOC-D mes-
sages. Finally at the (E)nd of the call, the network sends the total charge in an AOC-E message encapsulated in
the DISCONNECT or RELEASE message.
