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.

Configure Door Release Button on Grandstream GXV3275 to work with 2N Helios IP Force

Did you know that you can configure a programmable key on the Grandstream GXV3275 that will allow you to unlock the door via a peer-to-peer call from the 2N Helios IP Force to the Grandstream GXV3275 from the press of a button? Please see the following guide below in order to find out how to do this:

Step 1:
The first step is to start by web browsing to the IP address of the Grandstream GXV3275 using a web browser of your choice e.g. Google Chrome, Firefox.

Step 2:
Providing you have entered the correct IP address, you should see the following page prompting you to login to the web interface of the phone:

If you don’t know the username and password to login, you may need to consult an IT administrator.

Step 3:
Providing you have entered the correct username and password, you should see a few different settings to choose from. You will need to navigate to ‘Account’ using the top navigation bar, then ‘Call Settings’ using the navigation bar to the left hand side.

Step 4:
You will need to scroll down to the ‘Programmable Keys’ section which can be found near the bottom of the interface. You will need to set ‘Key Mode’ to ‘Dial DTMF’ using the drop down list.

Step 5:
For ‘Name’, you will need to enter a suitable name that will be displayed on the door release button on the phone.

Step 6:
For ‘DTMF Content’, you will need to enter the code that is set under ‘Switch Codes’ on the web interface of the 2N Helios IP Force. The default switch code that is set on the IP Force is ’00’.

Step 7:
Because the Grandstream GXV3275 and IP Force are peer-to-peer calling, you won’t need to worry about the ‘Dial DTMF Condition’. The default option should be set to ‘Incoming/Outgoing Call’. You can go ahead and leave that as the selected option.

Step 8:
Once you have configured all of the above options, you can go ahead and hit the ‘Save’ button at the bottom of the page. You should then be taken to the top of the page prompted to apply the configuration changes.

Firmware/System Version Used:

Grandstream GXV3275 Android Phone: System Version: 1.0.3.144

2N Helios IP Force: Firmware: 2.18.1.27.8

– Plug it in again and leave it. The LED indicator on the RTX repeater will then flash slowly (This means the repeater is ready for manual registration).

– Press the paging key on the W52P base until the “Handset” LED light on the base starts flashing.

– The LED on the RTX repeater will now change to flash faster than it did before.

3) Assign a repeater number to the RTX repeater from 2 to 7, for up to 6 repeaters. (The W52P takes repeater number 1)

– Dial #*9 on the W52H ‘Handset’, it will stay on this call for the duration of this procedure. The LED on the repeater will be lit solid.

– Press a number between 2 and 7. The LED indicator on the repeater will flash a corresponding number of times and then stay solid.

– Accept the registration by pressing the * key and end the call on the W52H ‘Handset’.

4) Configure the repeater:

– Connect this repeater to the RTX USB cable, power supply and your PC.

– Load the RTX software on the supplied CD.

– Type the “RFPI” number you have written down into the “RFPI” box in the “Network Device” section.

– Tick the “Ignore Hop Control” box and optionally the “Monitor Beep” if you want that on (useful for testing).

– Increment the “RPN” number in the “Repeater” section. This need to go up by one for each repeater in this chain.
