SIP Parameters

SIP Parameters

Several simple parameters are available to configure N2IWF general behaviour for handling SIP calls. Each parameter is specified as a LogicApp service global variable. These parameters are all simple definitions, not complex types or N2SVCD rule engine rulesets.

Parameter Type Description
NO_ANSWER_SECONDS Boolean The number of seconds to send to the network for no answer timeout during call setup. If not specified or set to 0, the default value 30 will apply.
(Default: 30)
DEFAULT_FORWARDER_URI_HEADER String A header name to use as the default location for the redirecting party when determining the call direction. This may be specified with a trailing ordinal as per the SIP additional selectors.
MIDCALL_RELEASE_REASON String The name of a release reason to use when ending a call at interim interrogation due to funds exhaustion, etc.
ORIGINAL_CALLED_HEADER String The name of the SIP header in the outbound INVITE to place the originally-received called party in when a network translation applies during call termination.
CALLING_SC_HEADER String The name of the SIP header in the outbound INVITE to place the calling party’s CUG short code in during call termination.
