General

1. Can I apply for both a landline and a mobile phone?

Yes, you can, if your department will allow it. You will pay for both devices.

2. I already have a Vodafone landline phone but would rather have a odafonemobile phone (or the other way around). Is it still possible to switch?

Yes, you can. You can do so by contacting your telephone coordinator (log in with your U number and RU password). Do keep in mind that the fees will change as well.

3. I will not be working in my usual spot for the time being, but somewhere else on campus. Is it possible to get the exact same telephone services at this temporary location?

If you have a landline phone you can have it set up as a flexible workplace/Hotdesk telephone You can request this service from your telephone coordinator (log in with your u-number and RU-password).

4. I am unable to make international calls. Why is that?

Whether you can make calls to an external number depends on the traffic class that applies to your landline phone number.

If you have a mobile phone you can make calls within zone 1. Most of Europe is part of this zone. It is likely that the country you wish to make a call to is not included in your subscription. Read more about your mobiel – data abonnement of calls via the operator.

5. Caller ID when I call an external number.

Caller ID is turned on by default by Radboud University, but can be turned off. You request this by contacting your telephone coordinator (log in with your u-number and RU-password).

6. What are green telephones?

“Green phones” are present on campus. These are landline phones that are powdered by a telephone cable. This means they can still be used in case of a power outage. Green phones are placed strategically so that they can be used in case of disasters.

Landline telephony

1.Is it possible to forward phone calls from my landline telephone?

If your work phone needs to be forwarded to your home or mobile phone, dial *21 and then dial the number you want to forward to. For example *21XXXX for an internal number. Forward to an external number, add an extra '0' (e.g. *2100612345678).

Test if this connection works.

The call forwarding can be cancelled by entering #21 on the call forwarder.

Switch it on or off remotely?

If you are unable to forward your phone yourself due to the coronavirus, please send an e-mail request to telefoonbeheer-isc@ru.nl with the internal number and the external number to be forwarded.

We will try to realize this as soon as possible. You can deactivate the call forwarding yourself when you are back at your workstation by dialing #21.

For other options read the manual for instructions for all the options (pdf, 700 kB).

2. How can I change the arrangement of the function buttons or the display layout of my landline telephone?

A number of function buttons can be changed by you or by Telephone Services. Fill in the correct template for this (Mitel 5312 (xlsx, 36 kB)/Mitel 5340 (xlsx, 382 kB)) and send it to ict-helpdesk@ru.nl.
Certain function buttons cannot be changed because they are the same for everyone on campus.

3. I am unable to make international calls Service numbers also do not work. Why is that?

Traffic classes (pdf, 595 kB) are used to determine which destinations you can call. Your device is most likely set to make calls exclusively within the Netherlands. If needed, you can ask your telephone coordinator to adjust this.

4. How do I call an international number or service number through an operator?

If you do not have the correct authorisation and you want to call an international or paid service number, you can do this via the operator.
Dial 99 and you will be able to speak with an operator. Indicate that you want to request a call.

5. How do I call a 5-digit internal number?

Pick up the receiver and dial the 5-digit internal number.

Dial 0 followed by the external number, including the area code (for example: 0 – 026 1234567).

7. How do I make an international call?

Dial 0 and the country code (for example: 0 – 00country code). It is possible that you are not authorised (pdf, 595 kB) to make international calls.

Mobile telephony

1. I already have a private Vodafone or other mobile subscription. Can I also use this subscription for making free phone calls to Radboud and Radboud university medical center employees?

No, unfortunately not. The costs you incur will depend on your own subscription.

Whether you can transfer depends on a number of factors. Contact the ICT Helpdesk for this. Telephone: 024 – 36 22222.

4. I am unable to forward a call!

We are aware of this issue. Your mobile device options determine what causes you to be unable to forward a call. Consult the manual of your phone to see what the options are.

5. I want to know more about the data subscription.

If you have a smartphone, the default subscription consists of a data subscription and calls within the Netherlands and Europe.

Please note: There is a charge for data usage above 5 GB and for calls in zones 1 and 2.  Overview of countries zone 1/2 (pdf, 528 kB). Also read question 8.

6. I can't make calls in the RU buildings and/or I don't have a data connection.

Due to the construction of some buildings there is sometimes not a good range for your 5G/data. To overcome this, switch to your wifi.

  • Turn on wifi for data
  • Turn on wifi calls on your phone if that option is available.

7. I can't make calls abroad and/or don't have a data connection.

Check the settings below on your phone:

  • Is network selection set to automatic?
  • Is mobile data on?
  • Is airplane mode off?
  • Is the phone on 2G or 3G (this is still often the case abroad)?

No range yet? There are more areas with poor reception when you are abroad. Go to a different location and see if you have range.

8. What happens if I make calls outside of my subscription or use data outside of zone 1 (EU)?

There is a charge for data usage above 5 GB and for calls in zones 1 and 2.  Overview of countries zone 1/2 (pdf, 528 kB). A standard threshold of €50,- exl VAT has been established. You will receive an SMS when your limit of €50,00 is almost reached for data usage. If you exceed this limit you will no longer be able to use data.

You can still make and receive calls. PLEASE NOTE: these call costs will continue and will be charged!

Use wifi as much as possible to avoid going over your limit. Your limit runs per calendar month. Contact your telephone contact person if you regularly reach your limit. Maybe it is an option to adjust your subscription or your limit. Of course these costs will be passed on to you.

9. Can I see my usage?

No, that is not possible.

10. I have an internal 5-digit number linked to my mobile phone. Can I call people outside of campus using the 5-digit number?
