vismRtpConnGrpTable 1.3.6.1.4.1.351.150.20.1.1.1
This table defines attributes used to set up a static trunked VoIP connection between an endpoint and another endpoint on a remote VISM. The maximum number of RTP connections that can be established is based on the current codec template, which is vismAppliedTemplate(defined in CISCO-VISM-MODULE-MIB MIB) object. Before establishing the connection, endpoints on either VISM's should have been created and the line signaling type needs to be configured.

If it is set to 'true(1)' the packets will be sent three times else will only be sent once (this is used for reliable links to save bandwidth). This object will override the card level object configuration vismVoIpTripleRedundancy(defined in CISCO-VISM-MODULE-MIB MIB). The default value is 'true(1)' if vismRtpDtmfTransport or vismRtpCasTransport is true, else 'false(2)'.
OBJECT-TYPE    
  TruthValue  

vismRtpDtmfTransport 1.3.6.1.4.1.351.150.20.1.1.1.1.13

OBJECT-TYPE    
  TruthValue  

vismRtpCasTransport 1.3.6.1.4.1.351.150.20.1.1.1.1.14
This attribute defines whether the CAS(Channel Associated Signaling) bits need to be transported to the other endpoint. In the case of switching application, the CAS bits are backhauled to the Call Agent through xGCP-CAS protocol. Note that if the line signaling type is CAS the default value is 'true(1)', else the default value is 'false(2)'.
OBJECT-TYPE    
  TruthValue  

vismRtpVad 1.3.6.1.4.1.351.150.20.1.1.1.1.15
This attribute defines whether the VAD has to be applied on this channel, upon detection of silence. For algorithms that do not have VAD standards, Cisco-proprietary VAD can be applied and the generic SID (Silence Information Descriptor) packet as specified in I.366.2 standards can be sent to the other end. When the codecType is clearChannel VAD has to be off.
OBJECT-TYPE    
  TruthValue  

vismRtpICSEnable 1.3.6.1.4.1.351.150.20.1.1.1.1.16
This attribute is used to enable or disable the ICS(Idle Channel Suppression) for a connection. This can be specified while adding the connection and cannot be modified. When the ICS is enabled the DSP will look for the idle CAS (ABCD bits) pattern specified in ds0IdleCode in dsx0 MIB. If the idle pattern is present the DSP stops generating voice packets towards network side. By default the ds0IdleCode will be zero unless the user has configured it before adding the cid. If the ds0IdleCode is changed after the connection is added it will have no affect unless the card is reset.
OBJECT-TYPE    
  TruthValue  

vismRtpConnAlarmState 1.3.6.1.4.1.351.150.20.1.1.1.1.17

OBJECT-TYPE    
  INTEGER active(1), failed(2)  

vismRtpRowStatus 1.3.6.1.4.1.351.150.20.1.1.1.1.18
This object is used to create, modify or delete an entry. An entry can be created using the 'createAndGo' option. Before creating a RTP connection, the endpoint should have already been created. And the line signaling type should have been configured. For creating a RTP connection, vismRtpEndptNum, vismRtpLocPort, vismRtpRmtPort, vismRtpRmtIp and vismRtpCodecType need to be provided. For the other objects the default will be applied. The RowStatus would be set to 'active' by the agent while creating a RTP connection. While deleting a RTP connection the RowStaus will be set to 'destroy'. The RTP connection won't be deleted if there are still call going on the connection.
OBJECT-TYPE    
  RowStatus  

vismRtpLcn 1.3.6.1.4.1.351.150.20.1.1.1.1.19

OBJECT-TYPE    
  INTEGER self(1), highLevel(2), both(3), notFail(4)  

vismRtpPayloadType 1.3.6.1.4.1.351.150.20.1.1.1.1.21
This object specifies the payload type to be used, when adding connection(s) in VoIP Trunking. IANA (Internet assigned number Authority) values (0..95) are static payload and (96..127) are dynamic payload type. The values (128..255) are define here to accomodate any future extension, also 256 is chosen as a default value to avoid payload conflict bewteen gateways. The value of 256 indicate the DSP should use a assigned payload value for the codec.
