                 Key: ASTERISK-27461

             Project: Asterisk
          Issue Type: Improvement
      Security Level: None
          Components: Channels/chan_sip/Interoperability
    Affects Versions: 15.1.3, 14.7.3
            Reporter: Yasuhiko Kamata

[summary]
A patch for sending in-dialog SIP NOTIFY message
with "SIPnotify" AMI action for latest (14.x and 15.x) asterisk.

[detail]
asterisk has an AMI action called "SIPnotify" in order to send any SIP
NOTIFY message. We want to let the SIP phone answer or hold by using
this action, but some SIP phones, especially AudioCodes 4xx phone,
do not accept it.

According to our investigation, some SIP phones do not accept SIP
NOTIFY message if it's not an in-dialog (must have the same "From:",
"Call-ID", and tags as "INVITE"), so we created this patch.
