ITH telephony – a flexible communications solution for your business. How does SIP trunking work?
SIP Trunking is a technology that enables companies to communicate over the Internet using Voice over Internet Protocol (VoIP). It is an IP-based communications system that uses the Session Initiation Protocol (SIP) to provide voice and multimedia services. This solution is becoming increasingly popular among organizations of all sizes because of its cost-effectiveness and scalability.

By routing calls over an Internet connection instead of traditional phone lines, SIP channels enable many enterprise-level features, such as call forwarding and conferencing, without the need to invest in expensive equipment or additional phone lines. In addition, SIP links eliminate the long distance charges associated with traditional phone systems, making them much more economical for organizations with multiple locations.
Why switch to ITH tele?
- Cost savings – switching to VoIP reduces the cost of phone calls because it uses the existing Internet network infrastructure.
- Flexibility – The VoIP solution allows you to easily scale the number of phone lines according to your business needs.

- Mobility – The SIP trunk allows you to use your phone line from anywhere with Internet access, making it easier to work remotely and communicate more effectively with customers and business partners.
- Integration with other systems – ITH telephony allows easy integration with other systems, such as CRM and contact management systems, which facilitates communication and enables automation of business processes.
- Multi-user support – allows multiple users to use a phone line at the same time, making it easier to manage communications and increase work efficiency.
- Call archiving – The VoIP solution enables call archiving, which allows easy access to call history and facilitates auditing and cost accounting.
- Security – ITH tele offers a high level of security, as connections are sent over the Internet and can be encrypted to protect against unauthorized access to data.

What is needed to use SIP Trunk?
The most important requirement is a PBX system that supports IP or a VoIP service provider. This provides access to SIP trunking features and ensures that incoming and outgoing calls are routed directly through the local PSTN gateway. In addition, organizations need a broadband connection with enough bandwidth to handle voice traffic, as well as wireless access point controllers. To increase security, companies should also use a firewall router or VPN server between the office network and the VoIP provider’s network.

ITH telephony – Security and reliability
SIP links are designed to provide a more secure connection than traditional communication methods, such as analog or ISDN links, due to encrypted data transmission.
Utilizing encryption and authentication protocols, SIP trunk links offer an extra layer of security for businesses that need it most. They also provide increased scalability, as they can easily accommodate additional users or services if needed. In addition, they are highly resilient to connectivity problems thanks to the reliability of modern networks with automatic failover processes in the event of a single link failure.
This ensures that customers stay connected no matter where they are or how often their network connections may change!
Optimization of the company’s internal communication
SIP trunk is a type of business phone system that can provide a cost-effective way to stay in touch. Using Voice over Internet Protocol (VoIP) technology, companies can save money on traditional phone services while getting the same features and benefits as users of traditional phone lines.
