SIP interface configuration task list 453
SmartWare Software Configuration Guide 39 • SIP interface configuration
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
incoming 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.
Mode: Interface ISDN
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.
Mode: Interface SIP
AOC Over SIP (Optional)
This enhancement sends AOC information transparently from ISDN (or H.323) to SIP and vice versa. AOC-
D elements are hex-encoded and sent as application/QSIG content in SIP INFO messages during a session.
Mode: Interface SIP
