----------------------------------------

Hello Team

Any luck on this?

I noticed another thing, I tried the latest certified-asterisk and initiate a call from Asterisk to a tcp sip peer and it was sourced from the primary interface eth0 instead of eth0:0
I had a private IP address on eth0 and public on eth0:0, my asterisk is configured to listen on the public IP and it works as expected in UDP but in TCP I got private IP as source at the other side and also in the tcpdump on server.

> 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)
