Questions About Plans

Redspot IP telephony works in such a way that calls from you are transported over the Internet to our servers and from there on to the regular telephone network. You must therefore have an internet connection, but the other party must not.

You can thus call all regular telephone numbers and everyone can call you and that no matter where in the world you are without it costing you or those who call you extra.1 2

We believe that you should be free to choose how you want to make calls and thus freely choose equipment or app or a combination that suits your needs best. Learn more

Since most internet connections today are very good, you are free to choose which ever equipment or app you want to use as long as it supports SIP 2.0. 

For equipment we do recommend using well known brands like Cisco, Fanvil, Gigaset, Grandstream, Linksys, Polycom, Snom and Yealink since lesser known brands often aren't reliable enough because they have buggy firmware and don't put enough ressources into fixing the bugs.

The easiest and cheapest is to use an app on your smartphone or computer and there are a lot of different options. Most will work if they support SIP and are not locked to a provider. Learn more

For private use or a small business, we recommend the cordless IP phones in the Gigaset Go series that can be used with both IP telephony and ordinary analog telephony, can handle 2 simultaneous calls and can be extended with up to 6 handsets. Learn more

If you have analogue telephones you are very happy with, you can use an analogue telephone adapter. If your internet connection is slow, it can be an advantage that the adapter has traffic prioritization (QoS) so that it can prioritize your call traffic higher and thus minimize interference. However, it only makes sense if all your traffic goes through the router and you do not f.x. use WiFi in the router you have from your ISP. Learn more

For business use, the best choice is often a PBX that come in a range of different sizes and features. Learn more

Can I use the IP telephony equipment I already have?

If you purchased your IP telephony equipment yourself, you can typically just change the setup and use it with Redspot. If your ISP has supllied your IP telephony equipment, it's only rarely possible - ask your ISP.

No, Redspots plans are based on IP-telephony and thus don't use SIM cards. You will get a phone number and a password you will need for to enter into your App or physical IP-phone.

Normally, moving your number takes a week from receiving your power of attorney and payment, but we can do it from weekday to weekday in urgent cases.

You usually have one month's notice with your current telecommunications company and must therefore be aware that you may be charged subscription fee until the end of your notice period. If you want us to move your number at a later date, please state this on the power of attorney or the email you send us the power of attorney with.

Note that you decide when your Redspot subscription starts, so if you f.x. currently are without internet connection, you can wait to activate your subscription until you have internet again.

Please notice

It may be necessary to first terminate various additional services, or split them up before it is possible to move a number:

  • TDC Duet: Must be terminated / divided into 2 separate subscriptions first (mobile and landline.
  • TDC "Nummerbestemt ringning" and "extra number" must be canceled first or moved together with the main number (requires extra number subscription). Contact us for more info.
  • Extra numbers on ISDN must be moved together with the main number (requires extra number subscription) or terminated. Is it only an extra no. that is to be moved, it is possible if it is first changed to the main number and the extra numbers are then terminated. Contact us for more info.

You must be aware that you must not terminate your telephone number yourself and that you may be charged a fee by your current provider if you move the number before the end of the lock-in period.

You can use Redspot's IP telephony everywhere you have stable internet and it does not cost you or those who call you extra. No roaming charges. Ever!1

Note that a few countries and providers are blocking IP telephony including Belize, United Arab Emirates (Dubai, Abu Dhabi etc.), Oman (Muscat) and therefore a VPN is required to make IP-telephony work.

No, you can call all ordinary telephone numbers in the world and the other party does not have to have internet.

It costs the same as calling other Danish landline phones. It is free for Redspot IP-telephony customers to call each other.

Yes, if you have a analog landline, IP telephony or ISDN in a country where we supply telephone numbers.

Our subscriptions can be used on your smartphone, but as they require an internet connection, they cannot replace your mobile subscription.

Yes, you can either create a new subscription at that time or let the number replace your number with us.

Yes, you can make calls to anyone and receive calls from Redspot customers. If others call your number, your "old" phone will ring until the number is moved. Your IP-phone can though be called by using a small workaround. This may become relevant if you f.x. move from your current address before the number is ported.
