[asterisk-users] OT: Which SIP method to use for this specificbehaviour
?<BR></FONT><BR></DIV>
<DIV></DIV>Hello,<BR><BR>Let SIP extensions 1001 and 1002 belong to an
Asterisk calling group : whenever an coming call reaches this calling group,
both extensions 1001 and 1002 receive a SIP INVITE message which makes these 2
phones starting to ring. <BR><BR>When a callee picks up his phone, the other
extension receives a CANCEL or BYE message which stops ringing.<BR><BR>Is
there any option you can include in CANCEL or BYE messages so that the SIP
hardphones would understand it shouldn't have to log this call as it has been
replied by someone else ? <BR><BR>In other words, is there any Alert-info
option which can be used to pilot phones call history logs ?<BR>I didn't
dare to search myself in IETF archives, given the number of standards, SIP is
now including.<BR><BR>Regards<BR></BLOCKQUOTE></BODY></HTML>
