DID numbers, SIP trunking,
routing, and integration — managed.

VoipTower sells two products: DID numbers and outbound pools. Other destinations are available as a managed route on request, after the destination has been vetted. Number types and the current ETA for each country are on the pricing page; other types on request. Outbound pools are used as your caller ID when you call out. Both are delivered over SIP trunking to any PBX or dialer (3CX, Asterisk, FreePBX and others). We set up the SIP trunk, codecs and routing of your numbers to your PBX, and help on your PBX side — in the same chat. Your PBX, dialer and CRM stay yours. We help connect calls to your CRM through your PBX or dialer — free, in the same chat. CRM-side development stays with your team or your CRM vendor. Engineering support is included with traffic.

No — engineering is included with traffic. We set up the SIP trunk, codecs and routing of your numbers to your PBX; queues, business hours and IVR live in your PBX, and we help on the PBX side — in the same chat. We help connect calls to your CRM through your PBX or dialer. No engineering or integration fees, no per-hour billing; each number has a setup and monthly fee, listed on the pricing page.

Yes. VoipTower connects to 3CX, Asterisk, FreePBX and most SIP-capable PBX systems; the SIP trunk is configured by VoipTower engineering during onboarding, with no separate integration fees. We help connect calls to your CRM through your PBX or dialer — free, in the same chat. CRM-side development stays with your team or your CRM vendor. We have no referral or partner arrangements with PBX, CRM or dialer vendors — recommendations follow technical fit.

Managed voice in 25+ countries, with dedicated coverage in Germany, the United Kingdom, France, Canada, Poland, Czech Republic, South Africa, and Argentina; DID numbers in 50+ countries — see the pricing page. A direction or number type not on the pricing page is available on request.

Your request is reviewed within about 24 hours. The first number in a country takes 2 to 15 business days, depending on the country — the current ETA is on the pricing page. After that first onboarding, the KYC token is reusable for every later order — new countries, new routes, new numbers — so the company itself is not verified again. Some directions additionally require proof of local presence in that country; the document scope is shown per direction on the pricing page. Re-orders in a country you already use: from about an hour, up to 1 business day — a 5-minute form, then delivery from your allocated stock. A country you have not ordered in before still follows that country’s ETA.

It depends on the direction. VoipTower works on the standard B2B service offer. The minimum term of a DID number depends on the direction; it is shown on the pricing page and in the order form, and confirmed before payment. Outbound pools are billed monthly.

VoipTower routes CLI only for numbers purchased through VoipTower or ported in with confirmed ownership. Arbitrary caller ID is not routed, so caller ID on your calls is always a number you have through VoipTower — predictable caller identification and clear regulatory standing in destination countries.
