# ctasip parameters

To display a list of ctasip parameters, enter the following command:

ctasip -V

The following table describes these parameters:

Parameter | Specifies...
general.board | Board number assigned in the OAM API configuration file.
general.slot | Timeslot to use for SIP. This value can range from 0 to the number of SIP licenses and must be unique to each instance of ctasip that is running.
general.autoStart | When the value is a non-zero value, the op (open port) and sp (start protocol) commands run automatically when ctasip starts.
general.autoRelease | When the value is a non-zero value, nccReleaseCall is called automatically after receiving a disconnect event.
sip.to | Default To address (called) for nccPlaceCall and also a default address for nccRegisterUser. The default address is 127.0.0.1, which works for placing calls locally to another instance of ctasip. Change this address to the actual IP address of the host machine.
sip.from | Default From address (calling) for nccPlaceCall and also a default address for nccRegisterUser. The default address is 127.0.0.1 (refer to the description of sip.to).
sip.registrar | Default address for a SIP registrar. This parameter is optional. Specify a valid address for a SIP registrar if nccRegisterUser is used.
sip.contact | Default contact address for the nccRegisterUser. Specify a valid contact address if nccRegisterUser is used.
sip.auth.user | Default user name if authentication is used either by a SIP registrar or for outgoing INVITE messages.
sip.auth.password | Default password if authentication is used either by a SIP registrar or for outgoing INVITE messages.
sip.sdp.connection.networkType | Default network type in the connection portion of the outgoing SDP information.
sip.sdp.connection.addressType | Default address type in the connection portion of the outgoing SDP information.
sip.sdp.connection.address | Default connection address used in passing SDP information. If using a CG board and Fusion, change this address to the address assigned to the CG board.
sip.sdp.connection.port | Default connection port for SDP information. If multiple versions of ctasip are used, this address must be different. Note: When specifying this address, two ports are used: the even numbered port carries media, and the odd numbered port carries control information.
sip.sdp.origin.username | Default user name.
sip.sdp.origin.sessionId | Default session ID.
sip.sdp.origin.version | Default version number.
sip.sdp.origin.networkType | Default network type. IN means internet.

sip.sdp.origin.address | Default IP address.
mspp.hmp | Set to zero for Fusion.
mspp.nomedia | ctasip has the capability of running in a pure call control mode. Set this value to a non-zero value if only signaling is being used.
