Mitel DHCP

Have a curious DHCP problem. DHCP is supplied by a windows server over the WAN. We recently converted from VPN over DSL to private frame. Mitel IP phones at the remote sites were set to DHCP on the VPN and worked fine. Once we converted to frame, phones would not get an address from the Windows server. The private frame routers (Adtran) are set to relay DHCP requests and this works for the PCs but not the Mitel phones. Mitel phones work when statically assigned. Any help would really be appreciated.

Do you have your phones and PCs in the same DHCP Scope? If not, do you have routing between these two subnets done by the Adtran router or you have another router inside? If you have these two subnets separated, check both interfaces for DHCP relay. Also it would be good idea to take a sniffer and try to watch, if your DHCP requests reach the DHCP server, if it sends DHCP responses back to requesting devices, and if you receive them at your remote location.

Good luck,

Mike

Adtran is the only router, and it is set up with static routes between the subnets. The remote sites in question are 10.3.1.x / 24 and 10.4.1.x / 24. All routing works fine for the data and the phones when statically assigned. Sniffer is planned, just hoping to resolve before. Thanks for the response.
