What are the Mitel VoIP VLAN/QoS requirements or preferences for Cisco switches?

Thanks, but looking for exact Mitel requirements, as defined in their documentation.  There are some specific DHCP predefined options, etc.

I am not positive on the the DHCP options, but the rest will work. I use this QoS currently with an Asterix box, but I used to have an Inter-Tel one. Inter-Tel is owned my Mitel.

I am pretty sure that it is the boot server option, that and possibly world wide web server. All this does is direct the phones broadcast to the appropriate server when it is booting.

This is all the east stuff, you need to make sure your phone config files are right is the hard part. Especially if you are not familiar with it.

What happened with this?

Here is a paper I wrote for our techs. Very informal but this should help.

Mitel IP phone options. (This is with Mitel phones on a 5000 series phone system)
Set this up on the customers DHCP server& actually have them do it. These are DHCP options & option 128, option 129 and so on. They will most likely have to add these because they wont exist. This is common practice.
If you have to help them then you have to understand how an option is built. There are many different DHCP servers that might be being used. They could be using Novell, Microsoft, they may even be using their router or Linux. Basically, the person that is building them needs four things. The option number, the name (this can be anything that the customer understand), the data type (String, interger, ip address and so on) and finally the data that will be entered. These will be built once. Once built, you can add them to multiple vlans.
These MUST be built on every data Vlan the phones will be installed or the phone will never download the proper information. The phone always boots on the main untagged vlan and pulls the DHCP options. Then, it uses the information it downloaded and reboots. The phone will then come up on the vlan listed in the options. So, you must have all these options on the phone vlan as well. If that doesnt make since, read through it slowly once again, and it will.

DHCP options
Option Number      Name (Anything you want)      Data Type (This will only be used when building the option& not while adding them to the scope.      Data to enter
43 (this will be used to replace all the options below IF it will work)      Mitel phone options      String;      "id:ipphone.mitel.com;sw_tftp=(IPADDRESS);call_srv=(IPADDRESS);vlan=(YourPhoneVlanNumber);l2p=6;dscp=46"
(the l2p and dscp should be 6 & 46)

128      TFTP_Server      IP ADDRESS;      IP of the 5000 phone system
129      Phone_Server      IP ADDRESS;      IP of the 5000 phone system
130      Mitel_Ip_Phone      String;      MITEL IP PHONE
132      Mitel_Vlan      Unsigned Integer 32     this is 32bits or 4bytes      VLAN of the 5000 phone system
133      Mitel_Priority      Unsigned Integer 32 this is 32bits or 4bytes      6 (Always enter 6 here)

Make sure the customers switches support vlan tagging. They need to do the research into this but make them aware. Their VLAN router or switch need to support DHCP forwarding too.
Data port for phone system and voice mail should be tagged for the voice vlan and not part of the data network.
Data ports for the phones should be tagged for voice vlan and untagged for data network.
5200 series Mitel phones must have the priority of 6 set when using QOS and proper DHCP options.

For QOS we use tic46 or diff46 or dscp 46 or Precedence 6 (different layers I believe but same priority). . This will need to be set by the admin of the VLAN router. We also put the phone VLAN at the top of the priority list if the switch allows like hp. In the 5000 set the data type of service and the voice type of service to 184 on all connections. Usually p6000 and so on, there may not be more than one connection.


Have fun!!!!!
