    Looking to connect an 03 number to a username/password account? (NOT direct to URI?)
    Free03numbers ONLY redirects numbers to either a Landline or SIP URI. If you are looking to use a free03number on a VoIP Phone, Softphone or anything similar then you will need a Trunk.

    VoIP Yonder provides instant free trunks with the first 03 and 0800 number for free. You can connect a VoIP phone, Softphone (such as ZoIPer) to this trunk and recieve/make calls for free. As well as setup a PBX on the trunk.

    Outbound calls work on a PAYG model (from 0.4p/min UK landline, 1.2p/min UK Mobile)

Calls to 03 numbers are included in customer calling plans to 01/02

03 are ideal for calling card access numbers/High inbound because:

  • Billed exactly the same way as 01/02 (i.e. will have inclusive minutes to 03 from mobile if caller has inclusive minutes to 01/02)
  • Area independent (not fixed to one location)
  • Used more and more by major calling card operators

How many concurrent calls can be received on the numbers?
*Unlimited available. We start you off on 96 concurrent calls and increase this for free if you need more.

Can you provide vanity/memorable numbers as access numbers?
Yes, absolutely. However, we do charge for these initially (up to £150/month depending on the number). But, once you reach high volumes of traffic (over 250,000 mins/month) your numbers will be free.

Examples of vanity/memorable numbers we could offer you:

  • 03303 500 200
  • 03303 500 300
  • 03303 500 500
  • 03303 600 600

Please e-mail/contact us to discuss pricing on our vanity/memorable numbers.

Are there any conditions for taking up the numbers?
All we ask is for numbers to receive at least 1 answered call per month, or numbers may be withdrawn.
