Why does DHCP Status wrongly shows endpoints as Offline while they are Online?
-
Hello,
We have DHCP static set for all the Aastra SIP phones installed in the office. When I browse to Status > DHCP Leases I see that many of SIP phones are offline while they are really online.
This is confusing, ambiguous and wrong info no matter where the information comes from or how it's taken. It could be that when it gets closer to the end of the day and there are no packets transferring from the phones that they show offline on the DHCP Lease table. Is there a way to get pfSense 1.2.3 to properly display this info. To me Offline mean Offline.
Thanks

Thanks for the clarification. Why isn't the device in the ARP table in the first place? Do you think that is a fault of the endpoint device?

It simply may not have tried to communicate through the gateway in a while and timed out of the arp cache. It's quite common.

Except for it's not a computer and it's a phone which goes down and then it has to be plugged and unplugged and it's annoying to the user.
I need to find a solid workaround for this. So far, setting the register timeout for the SIP user on the phone didn't help. There is not option to renew to retry timeout for DHCP on the phone. So, maybe I can somehow send packets or pings to the phone?
Would the ARPING package help me at all?
***I still don't understand why an endpoint loose touch with the router and not try to re obtain it's IP. The phone is an Aastra model.

If that is the case, its lack of presence in the ARP table is probably not the cause of the issue, but another indicator that it is not communicating properly on the network.
If it were actually sending packets to the firewall, it would show back up in the ARP table.
arping wouldn't help.
