Description
If enabled, the unit will send out a NOTIFY with
event=conference when starting a conference.
If set to yes, unit will include c=0.0.0.0 syntax in SDP
when sending a SIP re-INVITE to the peer to hold the
call. If set to no, unit will not include the c=0.0.0.0 syntax
in the SDP. The unit will always include a=sendonly
syntax in the SDP in either case.
Defaults to yes.
If set to yes, the Cisco IP phone uses a different
random call-ID for registration after the next software
reboot. If set to no, the Cisco IP phone tries to use the
same call-ID for registration after the next software
reboot. The Cisco IP phone always uses a new random
Call-ID for registration after a power-cycle, regardless
of this setting.
Defaults to no.
If set to yes, all audio video transport (AVT) tone
packets (encoded for redundancy) have the marker bit
set. If set to no, only the first packet has the marker bit
set for each DTMF event.
Defaults to yes.
Specifies the lowest TCP port number that can be
used for SIP sessions. Defaults to 5060.
Specifies the highest TCP port number that can be
used for SIP sessions. Defaults to 5080.
The CTI interface allows a third-party application to
control and monitor the state of a phone that has
registered with the Cisco SPA 9000. With this interface,
an application can control a phone to initiate an
outgoing call or answer an incoming call with a mouse
click from a PC.
Provides the option to take the caller ID from PAID-
RPID-FROM, P-ASSERTEDIDENTITY, REMOTE-PARTY-
ID, or FROM header.
