IP phones rebooting 1616L

[busster]

Customer has IPO 500V2, running 8.1(63).

PRI trunking, all phones powered locally.

Phones have started acting strange. Periodically, without warning, phones go out of service, looking for IP address, reboot, and go back into service.

This happens regardless of phone status. Has happened during conversation and while idle.

No particular user/device. Random.

System has been running for at least a year without this happening.

Software version of the 1616L stations?

Is there a HTTP server available?

Just noticed that I can not manually assign the fileserver ip address.

Once saved, it loses it, No FileServer message after reboot.

 

[amriddle01]

That's because the DHCP server is responding with a file server address, so the phone ignores the address you entered, but as the address it's given it doesn't respond with the correct files the phone also ignores that. Seen it many times with Draytek routers

 

[busster]

phones appear to be using ha1616ual_3200.bin

When IP address is manually assigned, DHCP should be out of the loop. Same case. Fileserver address is always lost

 

[amriddle01]

You can assign just the call server and file server addresses and let the rest come from the DHCP server, done it countless times. But if the DHCP server responds with a field you statically assigned it takes the one from DHCP

 

[busster]

DHCP is provided by TimeWarner, doubt if they are sending that option.
Even when all options are manually assigned, when it reboots, fileserver information is missing.

 

[busster]

Router ip address also is not saved upon reboot.

 

[amriddle01]

Indeed, but that's a standard DHCP field, so that's to be expected

 

[busster]

So you are saying manually inputting all ip information in the phone, ip, mask, server, router, etc. DHCP server is still accessed and the fileserver ip address provided?

 

[amriddle01]

No it shouldn't, but this is Avaya

 

[busster]

okay, unplugged two phones from network.
restarted and manually assigned all ip fields.
reboot
router and fileserver addresses not saved.
Impossible to get from dhcp, no network connection.

 

[amriddle01]

Why not stick a laptop on there with a HTTP server running and make sure they've upgraded then

 

[intrigrant]

If you enter IP data manually on the phone like
Phone ip == 0.0.0.0
CallSrv = 192.168.43.1
Gateway = 0.0.0.0
Mask = 0.0.0.0
FileSrv = 192.168.43.1
etc
Then the 0.0.0.0 values are filled bij DHCP during boot and the phone tries to reach the fileserver but if it fails it will erase the manually entered data and start looking for the CallSrv, if that fails too the phone reboots but the FileSrv address stays erased.

As you say it was stable for a year then there has been firmware updates deployed on the routers/switches or replacement of hardware or there is a device added in the network acting as a BootP/DHCP server. BootP and DHCP protocols are very similar protocols and a mix of those can really mess up stuff.

I am having the same issue with 1616 units today, did you find a fix ?

 

[busster]

Went into each phone and statically assigned an IP address. Went into router and changed DHCP scope to keep the range of ip addresses just for phones.

Thankfully is was a small office of 10 phones, so not a big deal. No problems since.

Same hardware as before, same software.

 

[dtracey]

not working for me. I think its the firmware version. I have a 1616 on another firmware and it works grand. Looks like I will have to setup a http server and roll back the firmware.
i am manually assigning all the IP details but the gateway and file server will not save.
