DHCP Issue with 3com switch and Inter-Tel 8662 Handsets
Hi All,
I have a crazy issue relating to nter-tel (mitel) 8662 VOIP handsets.
basically I have a 3com 4210g 24port POE switch (latest firmware)
a SBS2003 server directly plugged into it running DHCP
all the clients ranging from XP to W7 can all connect to server and pickup a DHCP address fine.
any DHCP capable device plugged into the switch pickup a IP fine, this includes printers and such like.
A test handset from Polycom and a cheap Grandstream VOIP phone both pickup DHCP ip address fine.
when I plug a Inter-tel 8622 handset into the switch it gets stuck at trying dhcp over and over.
If I manually set the handset IP I cannot ping it from anywhere on the network
If i plug a PC into the PC port on phone I cannot ping anything.
If i remove the 3com switch and replace it with a cheap netgear switch and use a POE injector to power the phone, it gets a IP perfectly.
If I power the 3com switch off and on again with the phone plugged in it will get a IP!
so basically DHCP works perfectly for every device under the sun bar intertel IP phones.
Its a very basic setup to the level that even I rip the switch out and plug in lonesome into a DHCP capable router it all works happy and I can pickup a DHCP address on every port, apart from the intertel phoens which get stuck.
I dont need any fancy setup on the switch as it trully is a basic site with a small number of users and a SBS server.
any suggestions or advice would save me pulling my hair out any further!
Thanks
Neil

Managed to get somewhere..
I deleted the default interface vlan 1 of the 3com switch and the phone came alive.
no what combination of tagging / untagging on the ports or manual configuration of VLAN id's on phones seemed to work.
As this switch is purely to run the IP phones and a few PC's / Printers in a small office I can live without the default VLAN interface but will play further.
I will credit the points to you from_exp.
