Nortel i2004 VoIP Phones on Cisco 3560 Switch 1

[tex52]

Can someone give me some insight on the best way to configure Cisco 3560 switches with the Nortel i2004 phones? I have configured them for the Cisco VoIP phones before but just wondering will it be the same. Thanks for any help!

probably just like any other Cisco switch. Just config the port for the same VLAN that your phones are on.

I hard set to 100 full even tho Nortel says auto/auto. If the phone doesnt come up then you can try auto/auto until it reaches the server, once it does then you can switch to 100 full.

Thanks MG2005,

I have never configured a Cisco switch for any Nortel VoIP phone. I usually use the switchport voice vlan # for the Cisco's, will the Nortels work with this?

For some reason the phones arent getting IP address's from the Switch's dhcp server even though i can get a client to obtain one.

I I thought you did

i had issues getting DHCP to work with Nortel phones as well, so I just statically configured the IP's, along with the TN's.

I would setup a new Voice VLAN for the Nortel phones, but the exisiting Cisco voice VLAN should work. But DEFINITELY make sure your voice and "data" are on different VLAN's

Just to clarify, I am not currently using any Cisco phones, that was at a prior job that I worked with those.

I really hope to get the dhcp working though, we are going to have many call center agents using these.

On the DHCP, how do I get the DHCP server to only serve our addresses on the voice vlan and not the data vlan? Thanks!

 

[MG2005]

theres a unique class identifier built into the IP phone, and you confog options on teh DHCP server to make it "internet-aware"

also remember, if you do partial DHCP or Full DHCP you still have to go to the phone and manually enter the TN and node ID (sucks I know, dont know why this is the case. Unless it has changed since i installed my equipment 2 years ago or so, I use mostly Cisco VoIP now)

i have a good doc on this stuff, IP line Description, Installation, operation Doc# 553-3001-204

voice vlan uses cdp therfore it will not work on nortel phones. u just define the port as a dot i q trunk and only allow the vlan for the phone and computer on the port. Then you manually define the vlan # in the phone or use vlan auto discovery. which works off dhcp. dhcp works fine on the Nortel phones. I have set it up many times. In my opinion Nortels method is better than cisco since they can allow ther phone to come up in the proper vlan without having to be on their own priopritary switch by using a open standard DHCP. If you need more info on setting up DHCP refer to the data networking for voip book specifically the appednix.

 

[MG2005]

im not a big fan of Nortel's IP stuff. DHCP is practically pointless with them cause you still have to go to the set and manually enter something. Kind of defeats the convenience of DHCP in my opinion (if this is still the case)

Hey guys. We have a simmilar problem here. DHCP does not work for the i2002 and i2004 over the cisco switches. I have had our CCIE working on this for a while now. Played around with DHCP setting on the dhcp server as well but no luck.
Will let you guys now as soon as we find the solution.
PS. does anyone run i2050 softphones? how is your quality? We used the Liberation headsets and they are crap - the users can hardly hear - so i installed a cheaper version and it works fine. The other problem there is is i keep getting jitter errors on the 1000M - the users complain about breakups - this is in a lan inviroment - running 100mb full duplex over cisco 2950 - anybody had this?

I use DCHP via cisco switches without any problems. The problem is the DHCP server in cisco. You have to use a another device that supports vendor specific information and cisco doesn't support that nor the proper DHCP relay function if it is a pix. I never use DHCP in cisco, I use a firewall that is trunkated into the VLAN and deliver the DCHP offer from the FW. The problem is that default the ip phone is configured without a vlan so you have to configure each and every phone if you use VLAN to automatic or manual. The i200X phones supports more than one DHCP req. So you can setup a DHCP with specific VLAN information on the default VLAN, then the phone askes again on the right VLAN and gets the rest of the information....

i do like the i2050 softphone alot. Works great at teh office, and even at hom eover a secure Cisco VPN software connection. Which is basically voice over internet and surprisingly it works great, considering you cant really manage QoS over the internet as you could on your IP network

dixiedogger or anyone else,

I configured my switch port as a dot1q trunk port and the phone for the vlan i wanted it on but now cannot get my client computers that are connected to the phone to be able to access our data network. I did get the phones to pull a dhcp address from the Cisco switch succesfully with no probs. Any suggestions? Thanks.

 

[dixiedogger]

the vlan u want the computers to be should be the native vlan on the port. Thus any untagged traffic is in that vlan.

We are getting a CCIE in next week to sort our Cisco's out. Our DHCP is also not working and the QOS on some 2950 is not working to well. Will post what we did - mabe it helps.
