Below are some instructions on how to factory reset and RTX4002 repeater:

1. Power off RTX Repeater

2. Power on the RTX Repeater for between 1-5 secs (ie 2 secs) then power off

3. Power on RTX Repeater for between 25-35 secs (ie 30 secs) then power off

Now the RTX Repeater should be reset, power it back on and the light should be blinking slowly.

When you receive an inbound call from an ISDN line (BRI or PRI), the calling party number (caller ID) arrives in a non-country specific format and it is up to your phone system or gateway to format it correctly for the area it is located in.

In the UK this means caller IDs for national numbers will be missing the leading zero and caller IDs for international numbers will be missing a leading double zero.

E.G. where you expect: 07123456789 you'll get 7123456789

Within the ISDN q.931 signalling when a call comes in, there is an element for passing information on the type of the number.


An ISDN PBX will generally put a zero onto the start of national numbers and double zero onto the start of international numbers in the UK.

The problem is, in SIP there is no such header as type-of-number. The caller-id will just be presented as passed. Meaning you'll see caller-ids on phones with missing zeros.


To fix this problem, a Vega gateway can add in the national & international prefixes on to caller-ids.

The settings can be found in the web interface or from the command line.

At the command line interface, for the UK you'll want to set:



In the web interface, these settings are in the Expert section, SIP page and SIP-Advanced link near the bottom:

They are:

  • National Prefix - set to 0

  • International Prefix - set to 00


Then the Caller-ID presented on SIP calls should be correct.

Note, more information on this can be found on page 171 of the Sangoma Vega admin guide:

The following guide shows how to connect a Plantronics CS520 (This will also apply to the other headsets in the CS500 series) headset to the Mitel 6865i desk phone to allow EHS functionality (the making and hanging up of calls via the headset button).

As well as the CS520 headset and the 6865i phone you will also need a Plantronics APS-11 EHS Cable.

1) Connect the APS-11 cable to the back of the CS520 stand, using the end of the cable that has both an RJ45 connector and a 3.5mm jack connector. Both connectors should be plugged in to the respective ports on the back of the stand.

2) Plug the other end of the APS-11 cable into the RJ45 socket on the back of the Mitel phone, you will need to remove the plastic spacer clip from the socket on the phone in order for it to fit. Please refer to the user manual for help with this.

3) Finally, you need to change some settings on the Mitel phone to enable the EHS functionality. Make the following changes via the menu on the handset itself (press the button with the gear icon to open the menu):

i) Go to Preferences - Set Audio - Audio Mode. Select Headset from the list and press the tick button to confirm.

ii) Go to Preferences - Set Audio - DHSG. Select the "DHSG is On" option and press the tick button to confirm.

That's it! The headset should now be able to make and receive calls using the EHS functionality.

If you have purchased these products from Provu, and can not get this to work, please contact our support team at and we will be happy to help!

Shipping Improvements

Today we have updated the order form in prosys for our trade customers. We now have some more flexible shipping options.

There are 2 main changes.

Automatic pricing for exotic destinations

Ireland, Northern Ireland, Scottish Highlands and Islands, Channel Islands, Isle of Man and Isle of Wight.

The order form will now correctly price shipments to all of the above destinations on APC, DPD and Parcelforce.

If you have a larger consignment going to these destinations, then it is worth giving our sales office call to check if we can get a better quote.


We now offer DPD as an alternative shipping option.

We have used APC as our primary UK courier for many years. They offer a really good service and good systems integration.

But we had some customers who wanted an alternative option.

DPD offer:
- an SMS with a 1 hour delivery window
- Competitive prices to Ireland, Northern Ireland, Scotland and Isle of Man on a 2 day service.
- More detailed online tracking.

Things to note:
1) Cut off for DPD is 3pm. APC is 5pm.
2) DPD not so price competitive on larger shipments.
