We are a company registered and based in Poland and are looking for a UK 033 business number to connect to our existing Slican PBX via SIP.
ould you please confirm the following:
Can a company registered and based entirely in Poland obtain and use a UK 033 number without having a UK office or UK postal address?
Can the number be connected directly to our existing Slican PBX using standard SIP credentials?
Can the same SIP connection be used for both inbound and outbound calls?
Can our assigned UK 033 number be presented as the outbound Caller ID?
How many simultaneous inbound and outbound calls can one SIP account handle?
Are there any additional charges for concurrent calls or channels?
What is the monthly cost of a UK 033 number?
What are your current outbound rates to standard UK landlines and UK mobile numbers?
Are incoming calls free or charged per minute?
Is the service prepaid/pay-as-you-go?
Is there any minimum top-up, minimum monthly spend or contract term?
Do prepaid funds expire?
Are there any setup or activation fees?
What verification or KYC documents are required from a Polish company?
We do not require a hosted PBX. The number would be used for normal business communication, mainly customer service, technical support and contact with UK distributors and customers.
Yes to all of it, and there’s nothing to register.
1. Poland-based company — no UK office or UK address needed. The 033 range carries no registration requirement, so you can order one today.
2, 3. Your Slican PBX — two ways to connect. Either we push incoming calls out to your PBX’s SIP address (set to VoIP, UDP or TLS+SRTP), or we issue you SIP credentials your PBX registers to (FlyNumber SIP). The credentials route is the one you want — same connection handles inbound and outbound.
4. Outbound calls leave with your 033 number as the caller ID.
5, 6. Each number includes 2 simultaneous calls at no extra charge. If you need more than that, tell us before you order and we’ll look at what’s possible.
7, 9, 13. $2.95/month, no setup or activation fee. Incoming calls are free — no per-minute charge on inbound.
8. Holding a UK number puts your UK calls on the domestic tier: roughly $0.004/min to landlines and $0.014/min to mobiles, billed per second. Live table on the rates page.
10, 11, 12. Prepaid, pay-as-you-go. No contract, no minimum monthly spend, top-ups from $1, and the balance doesn’t expire.
14. No documents for 033 — no address proof, no company registration. Just an account.
You mentioned that two simultaneous calls are included with the number. Could you please provide the available options and pricing if we wanted to increase this capacity to, for example:
5 simultaneous calls
10 simultaneous calls
We would be using the service with our existing Slican PBX via SIP credentials.
For the 5- or 10-call setup, do you need that many incoming calls, outgoing calls, or a mixture at the same time? Incoming and outgoing capacity are configured separately, so that detail matters for the quote. We’ll confirm the options and pricing for your Slican PBX before you order.
