Yealink T21E2 Updated Model

We recently announced a change to the Yealink T19PN as these have been updated to the T19PN E2. The same has now happened for the T21PN these are now T21PN E2.

We’ve tested the new Yealink T21E2 and provisions OK and is able to make calls. The chipset in the phone has changed but functionality-wise, it’s the same as the T21P.

There are a couple of changes you need to be aware of though:

  • It has it’s own firmware version and you cannot downgrade it to older versions (this will be a problem for ITSPs who have approved an older firmware on their platform).
  • It says “T21 E2” on the front of it.
  • It reports itself as a different model number when provisioning (which could cause problems for people who have implemented their own provisioning systems).

Which analogue gateway do I need? FXO or FXS

In the analogue telephony world there are two types of interface, FXO and FXS. What these mean is a cause of much confusion.

In summary:

 

    • FXO stands for Foreign eXchange Office. An example of an FXO device is an analogue telephone such as you might have on your desk or at home for making calls on. It is a device that accepts battery voltage (around 50 volts in the UK)

 

    • FXS stands for Foreign eXchange Station. An example of an FXS is a BT line on your wall that you plug your analogue telephone into. It is a device that provides battery voltage

 

 

Right away this naming seems backwards. Surely the telephone is better described as a “station” and the line as an “office”. I do agree, it is confusing but this is how it has been for much longer than I have been alive for.

 

Essentially, the naming is supposed to indicate what interface the device accepts rather than describing the device itself.

When it comes to choosing a VoIP gateway it is very important to select the correct interface. The wrong type will not work, no settings can control this, they are electrically different (one generates voltage, one accepts voltage).

Here is a diagram of a simple analogue telephone system (PBX) showing the interface names and how they are connected (click the image for a larger size):

As you can see, an FXS always plugs into an FXO and vice-versa. You cannot connect FXS to FXS or FXO to FXO. The same applies when you are replacing either phones or the lines with VoIP gateways.

The final diagram shows both types of endpoints replaced with VoIP gateways. In reality you wouldn’t replace both like this but the diagram serves to show what you need in either situation. If you are wanting to replace your analogue telephones with VoIP telephones, look at the left side of the diagram. If you are looking to replace your analogue lines with a VoIP service, look at the right side of the diagram:

One last (yet very important) note. I’ve shown Sangoma Vega gateways here, we sell these particular ones because they perform very well with BT analogue telephony in the UK. This isn’t true of all analogue-VoIP gateways, many designed outside the UK are made with the assumption that an analogue phone line in the UK is much the same as a “Bell” line in the USA. This isn’t the case, BT (and GPO before that) use their own standards defined many years ago. Although Sangoma is a Canadian company, the Vega gateway business was originally called Vegastream which was a company based in the UK. The old Vegastream office and most of their staff now form the UK Sangoma office and team of staff. So these gateways are developed in the UK by people who understand UK telecoms (as well as telecoms around the globe).

Yealink T19E2 Updated Model

We have received a new batch of Yealink T19PN from Yealink these have now been updated and are called the Yealink T19PN E2.

We’ve tested the new Yealink T19E2 and it seems to provision OK for us and is able to make calls.

Differences from what we can see:

  • It has it’s own firmware version and you cannot downgrade it to older versions (this will be a problem for ITSPs who have approved an older firmware on their platform).
  • It says “T19 E2” on the front of it.
  • It reports itself as a different model number when provisioning (which could cause problems for people who have implemented their own provisioning systems).
