Important Panasonic Provisioning Notification

Important Panasonic Provisioning Notification

We have been informed by Panasonic that phones manufactured in mid-2017 have a problem with the embedded client certificate.

Affected devices are all TGP600/HDV series manufactured from July to November 2017. The issue is that the certificate loaded into the device at the point of manufacture only lasts for one year instead of the usual thirty. This affects provisioning systems which secure connections by validating a device’s client certificate. As a result of this, at some point in July 2018, these devices will start to fail to provision if client verification is being used.

The fix is to upgrade the firmware of the device to the following versions (or newer):

Model Name Firmware Version Download Link
KX-TGP600 06.021
KX-HDV130 06.121
KX-HDV230 06.121
KX-HDV330 06.021
KX-HDV430 06.021

For customers using our provisioning platform, please contact us to organise upgrades of your phones. We can handle this automatically for you, but will require your consent to do so – phones will not be automatically upgraded.

For customers using other provisioning systems, please get in touch with whoever manages the system to organise the upgrades. If they require assistance, we are happy to help.

Panasonic has also provided a website for checking your phones.

We would like to apologise on behalf of Panasonic for any inconvenience this may cause. If you have any questions, please don’t hesitate to get in touch, you can call us on 01484 840048 or email support@provu.co.uk.

SIP-TLS with the Panasonic TGP600

The Panasonic TGP-600 DECT phone supports encryption of SIP signalling and audio (RTP) using the common SIP-TLS and SRTP methods supported by many VoIP platforms.

Configuration is very simple.  In the SIP Settings page:

Important settings are:

  • Proxy Server Port, Registrar Server Port, Presence Server Port.  The standard port for encrypted SIP is 5061 (rather than 5060 for normal plain-text SIP).  This depends on your SIP platform.
  • Transport Protocol. Set this to TLS
  • TLS Mode.  Depends on your platform but SIP-TLS is what I am using with an Asterisk PBX

All other settings on that page are the as normal.  You might need to alter some of the SRTP settings for voice encryption, on the VoIP Settings page:

  • SRTP Mode. This also depends on your SIP platform but Asterisk doesn’t handle negotiation of encryption so if it is being used at all, you need to get the phone to always use it, not attempt to negotiate.  In that case, this setting is set to “SRTP”

Certificates

By default the Panasonic phone is set to accept all certificates (meaning that self-signed certificates will work OK).  You can provision the phones to verify the certificate if you want to using the setting SIP_TLS_VERIFY_1_=”1″.  You need to ensure that you have loaded the necessary root certificate beforehand.

Why use TLS & SRTP?

Security:  If you are able to sniff the traffic on someone’s network (e.g. using Wireshark or tcpdump) then you will capture any VoIP calls going on.  A tool such as Wireshark can be used to extract the audio from the RTP packets on the network.  The SIP packets can be read in plain-English and can be used to ascertain certain things such as what extension numbers there are, who is phoning different numbers etc…

If the SIP traffic is encrypted then no-one can see it other than the telephone and the SIP server at the other end (much like HTTPS used by secure websites).

If the RTP stream is encrypted then the audio cannot be extracted from the network without access to the SRTP keys generated on each call.  If you try this using Wireshark, the audio file you’ll get out of it will contain only white-noise.  Because the encryption keys for SRTP are generated on each call and send within the SIP packets, it would make no sense to use SRTP without encrypting the SIP packets as well.

Hiding SIP from Application Layer Gateways:  Routers with SIP-ALGs built into them are the biggest single cause of issues with SIP, things such as one-way audio, calls cutting out, calls failing to connect etc…. can all be caused by a SIP-ALG on a router.  The job of the ALG is to keep an eye out for SIP packets going past and then to modify them in an attempt to fix them up to work through NAT.  But they nearly always cause more problems than they solve.  A less obvious attraction to SIP-TLS is that if the SIP traffic is encrypted, then a SIP-ALG cannot possibly see any SIP traffic going through it and much less, make any modifications to it.  This can be very useful for remote phones talking to a hosted PBX or a central office PBX.

The latter advantage is the main reason I am seeing people interested in SIP-TLS or already using it, rather than it’s intended use which is for secure calling.

Configuring the 2N Helios IP Uni with Panasonic KX-HDV130 with peer-to-peer dialling

We have recently been testing the 2N Helios IP Uni with the Panasonic KX-HDV130 entry level handset via peer-to-peer calling. After some very straight forward testing, we managed to get it working. You may use this scenario if you don’t want to involve an IP PBX.

Please note that this guide applies to the 2N IP range.

2N Helios IP Uni Configuration:

You will need to web browse to the IP address of the 2N Helios IP Uni which can be done by powering the unit via a Cat5e cable, then pressing the button on the unit five times once you have heard the initial startup tone. Then unit should then speak out the IP address of the unit to you.

Once you have obtained the IP address of the device, you will need to web browse to the IP address of the device e.g. ‘192.168.x.xx’. The default username is ‘Admin’ and the default password is ‘2N’. It is highly recommended that you change the default password before you start using the device.

Once you have logged into the web interface of the IP Uni, you will need to navigate to ‘Directory’ (blue tab), then make sure that the ‘Position Enabled’ field has a check in the box, then enter a relevant name in the ‘Name’ field under ‘User Basic Information’. Finally, you will need to enter the IP address of the Panasonic KX-HDV130. You can find out the IP address of the KX-HDV130 by navigating to ‘Menu’, ‘System Settings’, ‘Status’, ‘IPv4 Settings’, then ‘IP Address’ on the phone. The IP address should then be displayed on screen e.g. ‘192.168.x.xx’. The IP address should look something similar to ‘192.168.x.xx’ which needs to be inputted into the ‘Phone Number’ field under ‘User Phone Numbers’. It is important to make sure that you have included ‘sip:’ before inputting the IP address e.g. ‘sip:192.168.x.xx’. You will then need to apply the changes to the unit by clicking the ‘Apply’ button located at the bottom right hand side of the interface.

Please note that if you would like the ability to dial the extension number registered to the IP Uni, you will need to navigate to ‘Services’ (purple tab), then ‘Calls’ which is located at the top of the interface, then set ‘Call Answering Mode (SIP1)’ to ‘Automatic’ using the drop down list. You can then go ahead and apply the changes by clicking the ‘Apply’ button. You should now be able to dial ‘200’ from the KX-HDV130 and the Uni will automatically answer the call.

Panasonic KX-HDV130 Configuration:

You will need to start by finding out the IP address of the phone by navigating to ‘Menu’, ‘System Settings’, ‘Status’, ‘IPv4 Settings’, then ‘IP Address’. The IP address should then be displayed on screen e.g. ‘192.168.x.xx’.

You will then need to enable access to the web interface before you can web browse to the phone which can be done by navigating to ‘Menu’, ‘Basic Settings’, ‘Other Option’, ‘Embedded Web’ and then changing this setting to ‘On’. You can then go ahead and web browse to the phones IP address via a web browser of your choice e.g. Google Chrome.

When you browse to the IP address of the phone, you should be prompted to enter a username and a password. The default username is ‘admin’ and the default password is ‘adminpass’. Again, it is highly recommended that you change the default password before using the device.

You will need to click onto the ‘VoIP’ tab located at the top of the web interface, then click onto ‘Line 1’ which is located on the left hand sidebar under ‘SIP Settings’. Enter ‘200’ in the ‘Phone Number’ field, then the IP address of the IP Uni under ‘Registrar Server Address’. You will also need to enter the IP address of the IP Uni under the ‘Outbound Proxy Server Address’ and the ‘Service Domain’ fields. For the last two steps of the configuration for the KX-HDV130, enter ‘200’ in the ‘Authentication ID’ field and leave the ‘Authentication Password’ field blank.

That’s the end of the main configuration process for the 2N Helios IP Uni and the Panasonic KX-HDV130.

ProSys firmware provisioning

It has always been possible to manage firmware upgrades using our online phone management portal, ProSys. Support staff can do this very quickly by selecting from a drop-down box of available firmware on the portal.

What happens if you want a newer firmware, or just one which isn’t listed in the drop-down (yet!)?

Well, fortunately, it is possible to provide a custom setting in most cases to allow you to select the firmware you wish to provision to a device.

Proceed with caution…

You can use the “Quick entry” to add configuration settings to an individual device.
This allows you to add (key, value) pairs to the provisioning settings, giving you the power to provision firmware directly.

LDAP phonebook on Panasonic HDV phones

How To Setup LDAP/Active Directory phonebook on a Panasonic HDV (130,230,330) SIP phone

LDAP (Lightweight Directory Access Protocol) is commonly used with SIP phones to store contact lists or phonebooks. Many modern SIP phones can connect to an LDAP server and it is my recommended method of implementing a shared phonebook (simply because of cross-device support).

I will assume you already have a working LDAP server set up. On a Microsoft server, LDAP is called Active Directory. OpenLDAP is commonly used on open source based systems. Both work the same from the phone’s point of view.

Here is a screenshot of some example settings from a HDV330 phone.

These settings are fairly standard in SIP phones (or anything that is doing LDAP searching). Without going in to too much detail, key points are:

  • Server Address: this has to include the protocol name ‘ldap://’ at the start. Or ldaps:// for ldap over ssl
  • Port: normally 389 for ldap
  • User ID: you have to specify a username & password. The phone will not connect anonymously. The user id has to be the full DN of the user. Exactly what this is depends on how your ldap server is setup
  • Name/Number Filters: these settings contain the searches that will be performed depending on whether a name lookup (the user typed in letters) or a number lookup (the user typed in a number). What goes in here depends on your ldap server set up
  • Name/Number Attributes: these are the attributes within your ldap database that you are using to store names and telephone numbers in
  • Base DN: where to start the search in your ldap directory (ldap is hierarchical so objects above this base will not be seen by the phone)
  • DNS SRV: this is used for service discovery, if you don’t know what it is then leave it set to No!
  • Note – you must specify a username & password, these phones will not bind anonymously. I wouldn’t recommend running an ldap server like that anyway as you are leaving yourself open to getting all your contact’s information stolen!Now on the phone itself, find the phonebook option and select it. You will probably be shown the internal phonebook by default, press the option to switch to ‘shared phonebook’. On a HDV330 you press the button circled in red in this photo:
  • Then you can use the search box to type in a name, matching entries will be displayed:On phones with programmable keys, you can configure a key for shared phone book. Set the key type as ‘phonebook’, set the parameter to ‘2’ (for shared phonebook) and give it a label if required.
