Because of spiral complications and the potential of proxy interference with services, some devices allow loops to be terminated by exhausting Max-Forwards instead of actively trying to distinguish between loops and spirals.
The following posting by Jonathan indicates that max-forwards has become the preferred mechanism. http://130.230.52.14/list-archive/sip/msg06165.html > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On Behalf > Of Mahipati Deshpande > Sent: Tuesday, February 14, 2006 6:33 AM > To: [email protected] > Subject: Re: [Sip-implementors] Query about Loop Detection // > > > Using Max-Forwards header it is not possible to judge > looping.
