[asterisk-users] DHCP Failure screws up system

[Doug Lytle]

Maybe someone could point in the right direction.

I have a small facility that's running around 40 Polycom 301/501 phones, 
Asterisk 1.4.18 running under Mandriva 2007.1. 

The phones were assigned a DHCP address in the 10.10.10.x range.  Today, 
the DHCP server failed and to get them back online, I loaded the 
dhcp-server onto another system (Also running Mandriva) and copied the 
dhcpd.conf to that pc.

Now, after bringing that system online, the phones are bouncing up and 
down every few seconds with the following errors:

[May 19 14:32:23] NOTICE[3231]: chan_sip.c:15778 sip_poke_noanswer: Peer 
'4231' is now UNREACHABLE!  Last qualify: 39
[May 19 14:32:50] NOTICE[3231]: chan_sip.c:15778 sip_poke_noanswer: Peer 
'4276' is now UNREACHABLE!  Last qualify: 40
[May 19 14:33:02] NOTICE[3231]: chan_sip.c:15778 sip_poke_noanswer: Peer 
'4247' is now UNREACHABLE!  Last qualify: 38

I've got there qualify=500


A few seconds later they become reachable and then we start all over again.

When in the unreachable state (But I can still ping them from the phone 
system), they can't access the phone system).

Little info on the dhcp.

It has two interfaces, eth0 is for known hosts, eth1 is for unknown hosts.

The phones are assinged as unknown hosts.

The Asterisk system has two IP addresses attached to the eth0 
interface.  eth0:FWB1 is on the 10.10.10.15 where the phones register.

I've rebooted all the phones, Cisco switches and even the phone system.  
Makes no difference.


Any suggestions would be appreciated.
