Round robin DNS will cause every SIP packet to potentially go through a different static path, which will break things. > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Sent: Saturday, April 22, 2006 5:27 AM > To: 'Asterisk Users Mailing List - Non-Commercial Discussion' > Subject: RE: [Asterisk-Users] Connecting to a cluster of SIP servers > > > Although there maybe a better way, this would work: > > 1.
