SAS Inbound RTP Sink
This setting works around devices that do not play inbound
RTP if the streaming audio server line declares itself as a
send-only device and tells the client not to stream out audio.
Enter a Fully Qualified Domain Name (FQDN) or IP address of
an RTP sink; this value is used by the SPA9000’s streaming
audio server line in the SDP of its 200 response to an inbound
INVITE message from a client.
The purpose of this parameter is to work around devices that
do not play inbound RTP if the SAS line declares itself as a
“sendonly” device and tells the client not to stream out audio.
This parameter is a FQDN or IP address of a RTP sink to be
used by the SPA SAS line in the SDP of its 200 response to
inbound INVITE from a client. It will appear in the c = line and
the port number and, if specified, in the m = line of the SDP. If
this value is not specified or equal to 0, then c = 0.0.0.0 and
a=sendonly is used in the SDP to tell the SAS client to not to
send any RTP to this SAS line. If a non-zero value is specified,
then a=sendrecv and the SAS client will stream audio to the
given address. Special case: If the value is $IP, then the SAS
line’s own IP address is used in the c = line and a=sendrecv. In
that case the SAS client will stream RTP packets to the SAS
line.
Default: blank
Blind Attn-Xfer Enable
Enables the SPA9000 to perform an attended transfer
operation by ending the current call leg and performing a
blind transfer of the other call leg. If this feature is disabled,
the SPA9000 performs an attended transfer operation by
referring the other call leg to the current call leg while
maintaining both call legs. To use this feature, select yes.
Otherwise, select no.
Default:
no
MOH Server
User ID or URL of the auto-answering streaming audio server.
When only a user ID is specified, the current or outbound
proxy is contacted. Music-on-hold is disabled if the MOH
Server is not specified.
Xfer When Hangup Conf
Makes the SPA9000 perform a transfer when a conference
call has ended. Select yes or no from the drop-down menu.
Default:
Yes
