New Yealink T4X range, Available Now at ProVu

Yealink T4X

ProVu are excited to announce the launch of the new T4 series range of IP phones from widely recognised manufacturer, Yealink.

The T4 series offers the industry’s latest telephony features combined with intuitive user-interfaces, easy to use BLF keys, superior quality audio and large clear mirror style display screens.

The T4 series revolutionary design not only applies to the quality of its telephony but also to its attractive and stylish looks making it an ideal choice for the discerning user.

These sleek and elegantly designed handsets all feature a full-duplex speakerphone and Yealink’s Optima HD voice system providing rich, clear, life-like audio. Plus, the days of messy paper inserts are finally over, all the three models have between 6 & 10 BLF keys that can scroll to 3 pages, providing functionality for up to 27 buttons.

The phones also represent a sensible investment, with the T42G and T46G supporting POE with dual Gigabit Ethenet ports. The T41P also features PoE support but is designed for the more cost-efficient 10/100M Ethernet networks.

T4XX Features
The T42GN and T46GN are in stock now and the T41PN is expected to arrive in September.

If you have any questions please speak to the Sales Team on on 01484 840048 or send an email to contact@provu.co.uk

How to: Connect a Plantronics CS540 with a Yealink Phone

This is a step-by-step guide of how to successfully connect a Plantronics CS540 to a Yealink SIP phone (Compatible with T26P, T28P, T38G).

You should have:
– Plantronics CS540 Headset
– Yealink Handset with EHS capabilities
– Yealink EHS36 adapter.

(For a full list of headset and phone compatibility please view our headset compatibility chart)

The image below shows the contents of each box that will be required for this setup. They have been labelled for ease of idenitification and grouped according to which box you will find them in -see the key below.

Green – Yealink T38G Box
Yellow – Yealink EHS36 Box
Red – Plantronics CS540 Box

Step 1:
Once you have the correct parts ready, the next step is to connect the 3.5mm cable from the Plantronics base unit, to the EHS36 box. You can’t really go wrong here as they will only fit into one slot on each unit, but the picture below highlights where to connect them.

Step 2:
Connect the RJ12 cable from the EHS36 box to the EXT port on the back of the T38G. This port should be clearly labelled on the phone. See the picture below for illustration.

Step 3:
Connect the Plantronics RJ11 cable from the base unit to the Headset port on the back of the T38G. This port is labelled with a small headset icon, it is located next to the Receiver port, please make sure these are put into the correct slots. Again, the picture below shows how they should be connected.

That’s it! Power up the phone and the Plantronics base if you have not done so already. If this is a new purchase please allow a short time for the headset to charge before use. To charge simply place it onto the base in the very obvious slot.

If you have any problems after following this guide, please email support@provu.co.uk with details of your issue and a member of the technical team will be happy to advise.

Yealink Remote Control features

In an automated environment, it can be useful to control things without having to physically interact with them.

I refer, of course, to having to exert my energy on reaching to dial a number on my phone. You might well save yourself these exertions on a daily basis, so you can thank me later.

Here’s an example of dialling a couple of pleasant fellows:

http://user:pass@10.10.11.100/cgi-bin/ConfigMa
nApp.com?number=118118

If you try this on a more recent firmware, you may find that it doesn’t appear to do anything. Confusing at first but it seems there was a firmware change made for security purposes (can’t complain at that but it would be nice if the phone gave a 403 response when it does fail though!)

You now need to tell the phone what IP addresses to trust. If you web browse onto the Phone>Features page, you can find a text box labeled along the lines of “Trusted Action URI Server List”. You need to enter the IP addresses that the phone expects to receive requests from, as a comma-seperated list eg. 10.10.11.200,10.10.11.201

The first time the phone receives a remote request from one of these addresses, the phone does prompt you on screen to allow or reject the request (sorry.. you need to press the buttons this time!). I haven’t seen any subsequent prompts to confirm my consent.

If you want, you can also trigger key presses remotely:

/cgi-bin/ConfigManApp.com?key=OK
/cgi-bin/ConfigManApp.com?key=1
/cgi-bin/ConfigManApp.com?key=2
/cgi-bin/ConfigManApp.com?key=3
/cgi-bin/ConfigManApp.com?key=CANCEL

Isn’t that just great? You can build this into your CRMs or whatever else you can think of.

If you don’t have a Yealink phone to hand, you can browse the range: http://www.provu.co.uk/yealink.html

Now go and have some fun!

ProVu are pleased to announce the arrival of the new low cost Yealink T20E IP phone.

We believe this model is one of the most competitively priced quality IP phones available. It has all the same functionality of the popular T20P model including the same Auto Provisioning engine. However, as there is no POE support we are able to bring it to market at an even lower price (includes a UK PSU).

Very secure Yealink provisioning coming soon

Just a quick note to say that I was supplied a specially modified version of a Yealink T28P a few weeks ago which has HTTPS certificates loaded into it.

There are two certificate chains, one is used by the provisioning server to verify the identity of the phone. The other is used by the phone to verify the identity of the server. There is a list of a few popular certificate signing authorities you can buy a certificate from for the server identity.

This two way identification is what is required for a truely secure provisioning system. It protects against attackers attempting to obtain SIP configuration from our servers and protects against DNS spoofing/poisoning attacks against your phones.

We sometimes get asked for HTTPS provisioning and of course it is pretty simple to implement. But without these certificates it is fairly useless. It does nothing to guarantee the identity of the server or the client.

At the moment this is a Beta test, we will be rolling out this provisioning option as soon as we can, in the next few weeks. It requires Yealink to start supplying phones with certificates pre-loaded at the factory and requires a certain (currently test-only) firmware version.

If any of this is of interest, please let us know.

Yealink Handset Training Day

Last week, ProVu ran a Yealink handset training course down at the University College London (UCL). Roy from Yealink UK was also present to oversee the course and answer the commercial stuff.

The course is designed to cover the range of Yealink products and give a better technical understanding of the products. Attendees should be able to configure the Yealink phones and perform simple diagnostics to trace problems.

A wide range of topics was covered: ranging from the very basics of setting up a Yealink phone to configuring OpenVPN and discussing Yealink security features, amongst other things.

Here is a picture of me demonstrating the Yealink video phone making a video call with a Protalk Door Entry unit:

There was a Yealink goody-bag for people to take away at the end of the day which included a Yealink cup for you to SIP from.
