Why Should You Start Using SIP Trunk?
Large telecommunications operators massively abandon obsolete technologies and introduce IP telephony. In the near future, the full transition of operator telephone lines to https://didlogic.com/ sip trunk, and corporate PBXs to SIP protocol is just inevitable. In 2018, the number of SIP trunks already increased by 62% compared with the previous year. Let’s take a closer look at the principle of operation, the benefits, and mechanism of SIP trunks functioning.
What Is a SIP Trunk?
A SIP trunk is a dedicated telephone line established via an IP network through the SIP protocol. When making use of this standard protocol, the operator connects to the PBX one or more voice channels. In this case, telephone numbers assigned by the operator are called DID (Direct Inward Dialing) numbers and can be assigned to a single SIP trunk. In many countries, existing telephone numbers can be transferred to the DID format and then assigned to a new SIP trunk.
Advantages of SIP Trunks
Switching from standard telephony to SIP trunks provides a number of advantages:
- Reducing the subscription fee for the channel and DID number. The subscription fee for voice channels and DID numbers are significantly less than that for the same number of analog lines;
- Reduced call cost. Due to a large number of SIP-operators and high competition in this segment, the prices for SIP-calls are extremely reduced than those for normal calls. Some SIP operators even offer SIP trunks with unlimited packets;
- High-quality services. Achieved by connecting geographically distributed and even international numbers to a SIP trunk. Give your customers the opportunity to get in touch with you at a local number. People save money, and you accept calls to your PBX. Sales are growing because now customers are easier to contact youж
- Perform office relocation while maintaining a single number. A SIP trunk is not connected to a specific location. Now you do not need to notify people about the new number, correct advertising materials, business cards, and pay the operator for transferring the number.
- It is a scalable technology. If the number of calls is growing, you can quickly and easily add extra channels to an existing SIP trunk. One call to the operator is enough – and the service is activated immediately.
- The number of channels. One can select and pay money only for the needed amount of voice channels. Apply traditional ISDN / E1 technologies, you get at least 15 channels to be fully covered. And you can only expand the package of 15-30 pieces. For a small company, this is usually a waste of money.
Plan your telecommunication infrastructure in advance. Use modern technologies and SIP trunks as your major channel to interact with your partners and customers.
