VoIP telephony carries calls as data, over your internet connection, rather than over classic phone lines. Your team answers from the browser, mobile app, softphone or a SIP compatible IP phone, on a single business number, with an IVR voice menu, smart routing and real-time reports.
Capital Talker is the app that replaces the desk phone: you make and receive calls on the company number from your laptop, your mobile or straight from the browser, without buying IP phones. On mobile you install the app and take the company's calls without giving customers your personal number. The configuration lives on the server, not in the app, so a change to an extension or a routing rule applies immediately on every device the team uses. The softphone is not mandatory: any SIP-compatible IP phone connects to the same system, and in the same company some colleagues can work on the app while others use a desk phone.
A virtual number is an ordinary phone number that is not tied to a socket in the wall. It is the company's number, and you decide where the call lands: with one colleague, with several at once, or in a waiting queue. Customers call a single business number and reach the right person through the voice menu or skills-based routing, and when a colleague leaves the number stays with the company. You can receive calls on several numbers and treat each differently, with its own menu, schedule and team. The number your customers already know can stay yours: porting is regulated nationally, and we submit and follow the request for you. CapitalPBX numbers are business numbers, with a contract and an invoice; we do not offer temporary numbers for account verification.
CapitalPBX pricing starts at 60 EUR/month, or 48 EUR/month billed annually. The final price depends on the number of users and the options you choose. Details and calculator: capitalpbx.ro/en/pricing. Machine-readable version: capitalpbx.ro/en/pricing.md.
A business VoIP service is paid per team, not per phone. The price is made of three things: the base package, the number of users, and the options you choose. The entry plan covers 3 users, one administrator and two extensions, from 60 EUR per month or 48 EUR per month billed annually. Options are charged monthly on top of the subscription: most are priced per PBX no matter how many users you have, and the exception is the additional user, charged per person at 10 EUR per month. Calls to national fixed and mobile networks are charged separately, at 0.01 EUR per minute plus VAT.
A VoIP phone system is the company's phone system running over the internet rather than over analogue lines. It receives calls on the business number, passes them through the voice menu and distributes them to the team, in the browser, in the mobile app or on IP phones.
In practice, none; they are two names for the same technology. IP is the network the call travels over, and VoIP (Voice over Internet Protocol) is the name of the method that carries voice over it; the signalling protocol actually used is SIP. You will find both terms in providers' offers, sometimes on the same page. When you compare offers, look at the numbers, not the term: how many users the package includes (with us, 3 users in the Lite plan), what a minute to national networks costs (0.01 EUR/minute + VAT) and whether you can port your current number; you can, and under normal conditions porting completes in 3 working days.
Not all of them, and it is worth saying exactly which. Calls between users of the same CapitalPBX system, meaning extensions, colleagues and offices in different cities, are free, because they travel only over the internet. Calls to fixed or mobile numbers in Romania are charged at 0.01 EUR per minute plus VAT. International calls depend on the destination, not the distance, so it is worth asking for the exact rate for the country you call often.
The entry plan is 60 EUR/month, or 48 EUR/month billed annually, and covers 3 users: one administrator and two extensions. For a sole trader (PFA) or an SRL with two or three people, that is usually enough. Beyond that, each additional user costs 10 EUR/month, and options such as CRM integration or the call centre module 20 EUR/month each. Calls are added on top of the subscription, at 0.01 EUR/minute plus VAT to national networks. The contract and the invoice are issued to a company or sole trader (PFA).
PBX (Private Branch Exchange) is the system that manages a company's calls: extensions, routing, voice menu. In a VoIP PBX, calls travel over the internet instead of classic lines, and the system can run in the cloud with no hardware on site.
Yes, but not as a separately sold product. It means connecting your existing phone system to CapitalPBX Cloud PBX, through a static IP or SIP registration. The option is called the external IP-PBX connector and costs 20 EUR per month on top of the package you choose. We do not sell wholesale SIP channels.
Our configuration guide for IP phones and external SIP systems asks for codecs to be set in this priority order: PCMA (G.711 a-law), PCMU (G.711 u-law) and G.729, with an RTP packet size of 20 ms. It also asks you either to enable keep-alive or to reduce the SIP registration timer to 180 seconds. In the firewall, TCP ports 80, 443, 8080, 5060 and 5061 must be open, plus UDP 5060 and the range 10000-65535, and traffic must be allowed for the subnet 49.13.241.32/27. On the equipment, disable STUN, NAT Traversal and the proxy server, and disable SIP ALG on the router.
Less than people think. A call uses very little bandwidth, far below what a video call consumes, so an ordinary business connection carries a whole team's calls without trouble. Stability matters, not speed: a fast link with packet loss sounds worse than a modest, steady one. We recommend cable for fixed desks, good Wi-Fi or 4G for colleagues on the move, and prioritising voice traffic in the router if many agents talk at once.
Calls do not disappear, because the system lives in the cloud, not on your premises. From the panel you can set calls to redirect to the team's mobile app or to a backup number, and callers hear a message instead of a busy tone. In practice, an office internet outage becomes a comfort problem, not lost customers.
Not necessarily. You can start with just the app, on the phones and laptops the team already has. If you want physical devices, any SIP-compatible IP phone works. And if you already have a PBX you invested in, you can keep it and connect it to CapitalPBX through the external IP-PBX connector, at 20 EUR/month on top of the chosen plan; it does not have to be thrown away.
Number porting is regulated nationally, so the deadlines do not depend on the provider. Under normal conditions the process completes within 3 working days of the request, the operator you are leaving has one working day to respond, and activation takes at most one working day. During the switch, service is interrupted for at most 3 to 4 hours. We take on and manage the request, with one fair caveat: porting remains conditional on availability and on regulatory requirements. You are not obliged to port: if your current operator gives you SIP access, you can keep the number with them and connect it to CapitalPBX through SIP registration, with no forwarding fees.
Yes, international calls work normally over VoIP: the call leaves over the internet and enters the telephone network of the destination country, whether that is Germany or anywhere else. The cost depends on the destination and on your provider's rates, not on physical distance. The cost can also be capped: in CapitalPBX you set calling rules by direction, for the whole company or for specific employees and departments, and the default rule permits only internal calls and calls to the region of the outgoing number.
