Each SIP Trunk object is a child of the SIP Trunks object. It contains configuration parameters and status information for a connection to a remote SIP exchange.
The Configured SIP Binding used by this trunk determines whether it is a Basic SIP trunk or a SIP-T trunk. For a SIP-T trunk, "(SIP-T)" appears at the end of the name displayed for this trunk in the EMS tree view. A number of fields in this object do not appear for Basic SIP trunks.
For initial configuration of a SIP Trunk, you need to do the following:

Configured SIP Binding | Change Inactive | A set of parameters defining the connection between the MetaSwitch NE and the SIP device. Click on the search button to select from a list of Configured SIP Bindings with Usage set to Trunk. As a short-cut to select the Configured SIP Binding, you can type match details into the field and click on the search button to select from a list of items that match these details. Match details can be a text string, a wildcard string such as B*, or a range such as CA-FL. For more details, refer to the description of the Details panel in Operations Manual: Overview. |

|
Connected-switch LRN | Change | This field does not appear if Configured SIP Binding identifies a Basic SIP binding rather than a SIP-T binding. Specifies the LRN for the peer switch, which must be either a 10-digit number or left blank. This is used in generating billing records containing originating LRN information for incoming calls over this trunk group. For information about which LRN will be included, see Included LRN below. |
Override signaled LRN | Change | This field does not appear if Configured SIP Binding identifies a Basic SIP binding rather than a SIP-T binding, and appears only if an LRN is configured. Specifies whether or not the configured originating LRN should override the originating LRN in a JIP parameter in the received IAM for billing purposes.
If no originating LRN is configured on the trunk, this field is ignored. For information about which LRN will be included, see Included LRN below. Values:
|
Billing - incoming terminating CDR type | Change | This field is hidden if Supported call directions is set to Outgoing only. Specifies what additional CDR (if any) is output for incoming calls terminating on this NE using this SIP Trunk. Values:
|
Billing - generate additional incoming call CDR | Change | This field is hidden if Supported call directions is set to Outgoing only. Specifies whether an additional 119/0625 billing record should be output for incoming calls that are terminated on the switch, in addition to any CDR configured using the Billing - incoming terminating CDR type field. Values:
|
Billing - incoming tandem CDR type | Change | This field is hidden if Supported call directions is set to Outgoing only. Specifies what additional CDR (if any) is output for a tandem call routed through this NE using this SIP Trunk for the incoming leg. Values:
|
Billing - outgoing originating CDR type | Change | This field is hidden if Supported call directions is set to Incoming only. Specifies what additional CDR (if any) is output for outgoing calls originating from this NE using this SIP Trunk. Values:
|
Billing - outgoing tandem CDR type | Change | This field is hidden if Supported call directions is set to Incoming only. Specifies what additional CDR (if any) is output for a tandem call routed through this NE using this SIP Trunk for the outgoing leg. Values:
|
CNA billing for incoming calls - CIC | Change | This field is visible only if Supported call directions is not set to Outgoing only, and either Billing - incoming terminating CDR type or Billing - incoming tandem CDR type is set to CNA (720/0625) upon LNP query or CNA (720/0625) always. Specifies the Carrier Identification Code to use in CNA billing records generated for incoming calls on this SIP Trunk. Range: 0 - 9999. |
CNA billing for incoming calls - CNA billing number | Change | This field is visible only if Supported call directions is not set to Outgoing only, and either Billing - incoming terminating CDR type or Billing - incoming tandem CDR type is set to CNA (720/0625) upon LNP query or CNA (720/0625) always. Specifies the billing number which may be output in CNA billing records generated for incoming calls on this SIP Trunk. Either leave this field blank, or specify a ten digit number. |
CNA billing for incoming calls - include charge number | Change | This field does not appear if Configured SIP Binding identifies a Basic SIP binding rather than a SIP-T binding. It appears only if Supported call directions is not set to Outgoing only, and either Billing - incoming terminating CDR type or Billing - incoming tandem CDR type is set to CNA (720/0625) upon LNP query or CNA (720/0625) always.
Specifies whether the charge number should be included in CNA billing records. Values:
|
CNA billing for incoming calls - include calling number | Change | This field is visible only if Supported call directions is not set to Outgoing only, and either Billing - incoming terminating CDR type or Billing - incoming tandem CDR type is set to CNA (720/0625) upon LNP query or CNA (720/0625) always.
