Hello all, 

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)

Global Settings:
----------------
  UDP Bindaddress:        172.20.255.40:5060
  TCP SIP Bindaddress:    172.20.255.40:5060





Anyone has idea what could be the reason?
