High call quality via SIP TRUNK and simple handling of multiple calls simultaneously.

What is SIP TRUNK?

SIP TRUNK is a modern replacement for traditional digital telephony carried out on ISDN PRA/BRA lines, which allows multiple telephone calls to be made simultaneously via a so-called virtual channel (TRUNK). SIP TRUNK enables multi-channel voice transmission over the Internet and uses the Session Initiation Protocol (SIP) for this.

Why is it worth investing in SIP TRUNK?

Does handling dozens or even hundreds of calls at the same time require a huge financial investment? Not necessarily. With SIP TRUNK, anyone who needs to call even a very busy call centre has the opportunity to do so.

SIP TRUNK calls, which means that every customer can be reached

Fast response to offers and a helpful call centre are among the many elements that distinguish a professional company. In order for the company to keep growing, new customers are essential. By using a SIP VoIP package, you can be sure that anyone interested in the products or services offered by your company will instantly call the right person. No company can afford to lose customers simply because they did not call the helpline in time.

What benefits does the SIP TRUNK package provide?

SIP calls make it possible, above all, to reduce costs. In practice, this means free calls between all offices connected to a single VoIP system. Another advantage is the ability to analyse data in detail, enabling the company to operate even more efficiently. The greater the knowledge of the customer, the higher the quality of service. Flexible capacity, i.e. the ability to change the number of connections handled at the same time, is also an important feature. This is extremely important for businesses where periods of increased call volume occur periodically.

What is the difference between a virtual telephone exchange and SIP TRUNK?

A virtual switchboard is a service that enables telephone calls to be made and managed via the internet. It runs on the operator’s servers and does not require the customer to purchase additional equipment. Through the use of virtual telephone exchanges, the customer can benefit from various functions, i.e. call forwarding, call recording or call and video call recording.

The SIP Trunk service is dedicated to telephone exchanges – it enables incoming traffic from all public numbers on a SIP account and the presentation of outgoing traffic from the user’s exchange to be managed (allows telephone exchanges to be connected to the operator’s network using the SIP protocol). This allows the customer to use the PBX functions mentioned above.

The difference is that the virtual PBX runs on the operator’s servers, while the SIP Trunk service enables the customer’s PBX to be connected to the operator’s network. A virtual PBX is usually the cheaper and more flexible option, as it does not require the purchase and installation of additional equipment, while a SIP Trunk may be more beneficial for companies that already have their own PBX and want to use it by connecting it to the operator’s network.

SIP TRUNK and VoIP services – what do they have in common?

VoIP telephony and SIP Trunk are related because both SIP Trunk and VoIP use the SIP protocol to transmit voice.

The difference between VoIP and SIP Trunk is that VoIP is a generic technology that allows voice calls to be transmitted over an internet connection (the successor to IP telephony), while SIP Trunk services allow a telephone exchange to be connected to the operator’s network. With SIP Trunk, VoIP is one of the possible methods of voice transmission. EasyCall, as a telecommunications operator, provides VoIP internet telephony and a range of additional services.

What is a SIP account?

A SIP Trunk is an account with assigned telephone numbers that allows calls to be made using VoIP (internet telephony) technology. Authentication on a SIP account is done by entering a username and password. There is also a non-registration option – the IP address to which the internet packet with signalling and voice is sent must be entered.
