asterisk users - Jun 2005 - iax2 can't listen on virtual interface

Can anyone shed some light on this, I have two asterisk boxes using
heartbeat for failover.  Sip traffic works just fine with the virtual
IP but IAX does not.  For example on my servers one server has the
following:

eth0 = 192.168.1.95
eth0:0 = 192.168.1.2

the other server has:

eth0 = 192.168.1.220

if the first "Master" server goes down the second server will take
that virtal IP for it's eth0:0 but in either case the IAXY phones
cannot connect to this floating virtual IP but can connect to either
of the regular interfaces IPs.

Please let me know if I am incorrect or if ther is something I can do.

Yes you can.

Just tell iax to bind to that virtual address in iax.conf

He is using HA so I'm assuming he is running Master-Slave combo.

That means HA will start asterisk on slave after taking over the IP and
becoming a master.
Until that time, asterisk does not need to be running on a slave so
there should be no problems whatsoever.


If he wants to run asterisk in Master-Master that is a different story
but probably not what you want. Even then it is possible.
When becoming a master just script HA to unload chan_iax, assume the
virtual IP, substitute the bindip in iax.conf (sed will do just fine)
and then load chan_iax backup again. All that can be done while asterisk
is still running.

Regards

I don't think that will work on the box that doesn't currently own
that virtual address.

I think the only way is to make sure the bind address is 0.0.0.0

If you've already done that and it still doesn't work,
then I don't know, sorry.

Cheers
