asterisk users - Jan 2009 - iax2 bindaddress: how to reload so iax2 can bind to an alias IP

I'm trying to figure out how to reload iax2 (without breaking existing
calls) so it can listen on a new IP address (like "ip addr add local
..."). This alias IP is added/removed by a custom process (script) for
clustering purposes.

The iax.conf file contains "bindaddr=0.0.0.0".

I tried a "iax2 reload" (executed without errors or warnings) but
I'm still not able to connect to the alias IP from another Asterisk server
within the same LAN (no firewalls of any type in the middle).

On the other Asterisk server I run a "iax2 show peers" and get
"status UNREACHABLE" for the alias IP trunk (eg. 192.168.250.115 in
the example below).

However, if I specify a non-alias IP address on the other server's trunk
settings then a "iax2 show peers" shows a "status OK" (eg.
192.168.250.111 in the example below).

Just for your information, the IP settings on the server I'm trying to
connect to are:
# ip addr show eth1
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast qlen
1000
    link/ether 00:1d:60:b0:25:10 brd ff:ff:ff:ff:ff:ff
    inet 192.168.250.111/24 brd 192.168.250.255 scope global eth1
    inet 192.168.250.115/24 brd 192.168.250.255 scope global secondary eth1
    inet6 fe80::21d:60ff:feb0:2510/64 scope link
       valid_lft forever preferred_lft forever

This Asterisk server has version 1.2.30.

The other "connecting" Asterisk server has version 1.4.21.2.

Any ideas as to what I could try?

Is this right after bringing online the alias IP?
If so, you might try using arp-sk to broadcast an ARP packet to 
kick-start the IP lookup...
