I have swapped the phone and PC, the PC manages to get an IP address but the phone stays in DHCP DISCOVERY, I have upgraded the firmware to 1.04, released 2007 (SRW208P) and reset all settings to no avail. Both switched have been power cycled

<div class="content wysiwyg-content">
I've got a Mitel phone that is stuck in DHCP DISCOVERY. It is located in another building. That building is connected to the main building with a fibre link using a fast ethernet media converter The network map is shown below.<br />
<br />
I have tried other phones and they dont work however if I take the phone back into the office it works fine.<br />
<br />
I've called Mitel themselves and they have no idea what could be causing this. HP advised to try turning spanning tree off but this is all to no avail. PLease Help<br />

The only firewall we have is in the perimeter network and I dont see how it would affect this. The HP ProCurve has no VLANS configured except for the default one.<br />

Mitel IP Phone stuck in DHCP DISCOVERY

The Dynamic Host Configuration Protocol (DHCP) is an auto configuration protocol used on IP networks and an extension of the Bootstrap Protocol. DHCP allows for computers to be configured automatically to communicate with each other over an IP network without the need for manual setup by a network administrator. The implementation of DHCP relies on a DHCP server to hand out network configuration information to DHCP-capable clients that request an IP address (and other information required or useful in communicating with other devices on an IP network). In addition to an IP address, common configuration information served over DHCP includes a default gateway, subnet mask and DNS sever(s).

DHCP

Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, broadband telephony, and broadband phone service. The term specifically refers to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).  Examples of the VoIP protocols are H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), H.248 (also known as Media Gateway Control (Megaco)), Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Secure Real-time Transport Protocol (SRTP), Session Description Protocol (SDP), and Inter-Asterisk eXchange (IAX).

Voice Over IP

IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user.
