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)
asterisk 2878 asterisk  528u  IPv4 29757779      0t0  TCP 172.20.255.41:55627->10.200.14.29:sip (ESTABLISHED)
asterisk 2878 asterisk  530u  IPv4 19211854      0t0  TCP 172.20.255.40:sip->10.100.157.32:49227 (ESTABLISHED)
