[asterisk-users] Asterisk listening on undefined IP as per bindaddr

Hello all,

I am running asterisk on VMs with standby heartbeat configuration,
Heartbeat assigns a virtual IP on machine afterwards asterisk
is started. In the sip.conf, I have explicitly define
bindaddr= but sometimes I see packets coming from physical IP

I have both tcp and udp transport enabled

Here is the lsof -ni :5060 output

asterisk 2878 asterisk  613r  IPv4 40060683      0t0  TCP> (ESTABLISHED)
asterisk 2878 asterisk  528u  IPv4 29757779      0t0  TCP> (ESTABLISHED)
asterisk 2878 asterisk  530u  IPv4 19211854      0t0  TCP

 sip show settings

Global Settings:
  UDP Bindaddress:
  TCP SIP Bindaddress:

Anyone has idea what could be the reason?
