DESCRIPTION¶
Drops messages. This means, does no further processing in the Net::SIP chain and
does not send something back if the incoming message match the settings.
Some useful droppers are defined in Net::SIP::Dropper::ByIpPort and
Net::SIP::Dropper::ByField.
CONSTRUCTOR¶
- new ( ARGS )
- ARGS is a hash with key "cb" or "cbs".
"cb" is a single callback to be processed, "cbs" is an
arrayref with callbacks. If one of the callbacks returns true the message
will be dropped. If all callbacks return false the message will be
forwarded in the chain.
Returns a new dropper object to be used in the chain.
