> Hi,
> I am running asterisk on VMs with standby heartbeat configuration, Heartbeat assigns a virtual IP 172.20.255.40 on machine afterwards asterisk is started. In the sip.conf, I have explicitly define bindaddr=172.20.255.40 but sometimes I see packets coming from physical IP 172.20.255.41
> I have both tcp and udp transport enabled 
> Here is the lsof -ni :5060 output 
> asterisk 2878 asterisk  613r  IPv4 40060683      0t0  TCP 172.20.255.41:52381->10.100.210.110:sip (ESTABLISHED)
