Panasonic KX-HDV / KX-TGP / KX-UT — setting up for our PBX

Panasonic is the “office” alternative to the Chinese phones: the KX-HDV130 and KX-HDV230 desk sets, the KX-HDV330/340/430 with a bigger screen, the KX-TGP600 DECT system with KX-TPA60/65 handsets, and the discontinued but still widespread KX-UT range. All of them are configured from a web interface, and all of them share one trait that regularly makes people think the phone is broken:

⚠️ The Panasonic web interface is OFF by default. Until you turn it on from the handset itself, a browser pointed at the phone shows nothing. This is neither a network fault nor a router block. The setting is called “Embedded Web”.

The second trait is the factory administrator password: admin / adminpass, not the usual admin/admin.

The credentials, the network requirements and the universal values are on the overview page “Setting up SIP phones”. This page is about Panasonic only.

What you will need#

  • The extension credentials from the admin panel: SIP server, user name, password, port, transport — see “Credentials”.
  • The phone on the same network as your computer. Out of the box it takes its address over DHCP (“DHCP–AUTO”).
  • A computer with a browser on that same network.
  • Physical access to the device — the web interface cannot be enabled any other way. For the KX-TGP600 you need a registered handset: the base menu lives in it.

Step 1. Find the phone's IP address#

On the idle phone press Menu, choose “System Settings” → “Status” → “IPV4 Settings”. The “IP Address” row is the address of the phone on your network. The same “Status” menu holds “Line Status” (REGISTERED / REGISTERING / empty) — you will need it in step 4.

The System Settings → Status menu map of a Panasonic phone: Line Status, IP Mode, IPV4 Settings with the IP address Screenshot: KX-HDV130/230 Operating Instructions (Russian edition), p. 90.

On the KX-TGP600 the same path is dialled on the handset (Menu → Status → IPV4 Settings) and shows the address of the base unit — that is the one you need for the web interface. If the value is not set yet, the screen shows 0.0.0.0: the phone has not received an address, wait or check the cable.

Step 2. Enable the web interface and log in#

First open the web port from the device itself — it is closed by default.

KX-HDV130/230/330/430: Menu → “System Settings” → “Network Settings” → “Embedded Web” → “On”. The same item is in the basic settings: “Other Option” → “Embedded Web”.

KX-TGP600 (from a KX-TPA60/65 handset): Menu → “Setting Handset” → “Other Option” → “Embedded Web” → “On”.

KX-UT113/123/133/136/248: press Setup and dial the direct command #534, then choose “Enable” for Embedded Web.

Now open http://<phone IP> and log in:

Factory value
Address http://<phone IP>
Administrator ID admin
Administrator password adminpass
User account user, empty password — it has no line settings

Three consecutive failed logins close the web port again — then you have to enable it on the device once more. Only one account can be logged in to the web interface at a time.

When you are done, close the port again: the [Web Port Close] button in the web interface, or the same “Embedded Web” item set to “Off”. A phone on the shared network of the venue with an open web interface is one door too many.

Step 3. Enter the PBX credentials#

In the web interface open the VoIP tab → SIP Settings → Line 1 in the left menu and fill in the Basic block:

In the admin panel (“Extension credentials”) On the phone (VoIP → SIP Settings, Line 1)
SIP server Registrar Server Address and Proxy Server Address — the same address in both fields
Port 5060 Registrar Server Port and Proxy Server Port (factory value 5060)
User name (sip-…-<extension>) Phone Number and Authentication ID — in full, in both fields
Password Authentication Password
Transport UDP Transport Protocol in the Advanced block further down the same page
Extension number The line label is set separately, under Telephone → Line Settings

Leave Presence Server, Outbound Proxy Server Address and Service Domain empty — our PBX does not use them.

Press Save. The line restarts and goes out to register.

Optional: codecs, time, DNS, provisioning a fleet
  • Codecs — VoIP → VoIP Settings [Line n], the block with G.722 and G.711. Keep G.711 A-law, G.711 µ-law and G.722; the rest can be disabled.
  • Transport — VoIP → SIP Settings [Line n] → Advanced → Transport Protocol. Ours is UDP.
  • Registration lifetime — the REGISTER Expires Timer in the same block. The factory value is fine.
  • Enable DNS SRV lookup — leave it off: our PBX address resolves through a plain A record.
  • Time — the System tab, NTP and time zone. Without correct time the call history carries wrong timestamps.
  • Provisioning a fleet. The platform has no provisioning server of its own, but the phone can fetch a configuration by itself: Maintenance → Provisioning Maintenance. On a phone that came from a previous provider this section must be cleared — otherwise the phone downloads someone else's configuration over yours.
  • In configuration files the same fields are SIP_RGSTR_ADDR_n, SIP_PRXY_ADDR_n, SIP_AUTHID_n, SIP_PASS_n, PHONE_NUMBER_n — useful if the fleet is provisioned from your own server.

Step 4. Check the registration#

  • On the phone: Menu → “System Settings” → “Status” → “Line Status” should read REGISTERED. REGISTERING means it is trying; empty means the line is not configured.
  • In the web interface: the Status → VoIP Status tab — a table of lines with the number and the state.
  • In the admin panel (Telephony → Operators) the operator gets a green dot and the string the phone reported about itself. The status comes from the PBX and is refreshed at most once a minute.
  • A test call to a colleague's extension.

Factory reset#

The Panasonic administrator guide states it plainly: perform a reset before connecting the unit to a different phone system. A second-hand phone, or one from a previous provider, keeps those settings in a separate layer, and they survive a simple edit of the fields.

From the web interface (all models). The Maintenance → Reset to Defaults tab → the [Reset to Carrier Defaults] button → OK in the confirmation dialog. The unit reboots — even if somebody is on a call at that moment.

The Maintenance → Reset to Defaults page of the Panasonic web interface with the Reset to Carrier Defaults button Screenshot: KX-HDV130/230/330/430 Administrator Guide (Russian edition), p. 177.

From the device, on the KX-UT113/123/133/136/248: press Setup, dial #136, choose “Factory Settings” → “Yes” → “Yes”. This is a full initialisation: settings, call logs and the phonebook are all erased, and the phone reboots by itself. A separate command, #739, resets only the web interface ID and password — that is what to use when the administrator password is lost but the settings should stay.

KX-TGP600 (DECT). The base unit is reset with the same [Reset to Carrier Defaults] from the web interface; while it resets, the STATUS indicator flashes quickly — wait for it to stop. A handset is de-registered separately: Menu → “System Settings” → “Cancel Handset”. The factory base PIN is 1234 (the “Change Base PIN” item).

What is erased: line accounts, network settings, language, the phonebook and the logs. The firmware stays. After a reset the web interface is off again — start from step 2.

If the phone does not register#

  1. The server address is filled in only one field. Panasonic has two: Registrar Server Address and Proxy Server Address. Put our address in both.
  2. The user name is not entered in full. Authentication ID and Phone Number need the whole sip-…-<extension>, not the short extension number.
  3. The password is stale — somebody pressed “Reset password” in the admin panel. Issue a new one.
  4. Transport Protocol is not UDP (VoIP → SIP Settings → Advanced). A second-hand phone often keeps TCP or TLS there.
  5. The port is not 5060. The Panasonic factory value is 5060, but 5070 shows up in vendor examples and at some providers; check both port fields.
  6. The settings “come back on their own” — the previous provider's provisioning is running: Maintenance → Provisioning Maintenance, and it is best to do a full reset straight away.
  7. The web interface stopped opening halfway through setup — three failed logins close the web port. Enable “Embedded Web” on the device again.

The generic network causes (ports, SIP ALG, guest Wi-Fi) are listed in “If it does not register” on the overview page.

FAQ#

The web interface of a Panasonic phone does not open#

That is by design: the web port is closed from the factory. Enable it on the device — Menu → System Settings → Network Settings → Embedded Web → On (on the KX-UT, press Setup and dial #534), then open http://<phone IP> and log in as admin / adminpass.

The web administrator password is lost#

The KX-UT has the #739 command, which resets only the web interface ID and password and leaves the line settings alone. The KX-HDV and the KX-TGP600 have no such command: only a full reset (Maintenance → Reset to Defaults) is left, after which the account has to be entered again.

The phone came from a previous telephony provider — what now?#

Reset it first (Maintenance → Reset to Defaults → [Reset to Carrier Defaults]) and only then enter our credentials: the Panasonic administrator guide explicitly requires this before connecting the unit to a different phone system. The “carrier” settings live in a separate layer and survive a plain edit of the fields — the phone will stubbornly keep talking to the old server.

Panasonic registers, but the call drops after half a minute#

That is not registration but the media stream: almost always SIP ALG on the venue router. Turn it off — see “The venue network”.

How do I set up KX-TPA60 handsets on a KX-TGP600 base?#

The line accounts are created in the web interface of the base (VoIP → SIP Settings), and a handset is bound to the base through Menu → System Settings → Handset Registration on the handset itself; the factory base PIN is 1234. One line can be assigned to several handsets, in which case the call rings on all of them.
