Avaya 9608 DHCP issue

[sysadmin87]

We are setup with mostly digital phones however we do not have additional digital ports in some of the office so we bought about 5 IP phones to run data to instead. I was able to configure the 1st two without any issues however now when I plug one in, it just stay on DHCP and never gets an address. I have tried this on all 3 of the remaining phones. This was kind of a last minute thing so I have not configured a separate VLAN for the phones yet.

I know this won,t fix the issue but with only 3 left you could static those remaining phones

How many licenses do you have.
How is you DHCP scope set up?

Really need more information

 

[sysadmin87]

We have 10 available licenses. I don't think that is the problem because it is not even getting a IP address to contact the server. I have a Windows Server 2012 serving as the DHCP server on a 192.168.1.0/24. I verified that we are not out of available IP addresses.

IS option 242 setup ?

 

[sysadmin87]

It was not previously setup. I just set it up but I'm still seeing the same issue.

If option 242 is not available, the phone would still get an IP Address and will then end with 'no callsv address' (or httpsrvr address, can't remeber exactly..)

Put the Call Server and HTTP Server address (IPO Address)in the phone. You won't need to setup your 242 scope option. Not worth the time for 5 phones.
When you decide to expand your network to include more phones you'll need a voice vlan for additional voice traffic. Then setup your DHCP server 242 option and LLDP on your switches.

same advise I gave earlier seeing he has only 5 phones

I had the same issue with my IP phones when windows is handing out DHCP. this is what i changed. Properties > Advanced Tab. In advanced there is an option for conflict detection attempts. By default it is set to zero. Set it to two or three.

 

[sysadmin87]

I tried to adjust the DHCP setting from 0 to 3 but this did not resolve the issue that I am having.

 

[joe2938]

static them and be done with it

 

[Okkie26]

Did you try another switch port?

Maybe there are vlans present, and you are now in a vlan with no DHCP server.

Did you also try to clear the phones?

 

[sysadmin87]

I have tried multiple ports on the switch and multiple cables and also multiple power injectors.

Are these used phones? If so, they may have inappropriate VLAN ID already set. Plug a laptop into same switch port and see if it gets an address.
