In recent years, many companies have begun transitioning to VoIP services to increase efficiency and reduce costs. In doing so, they have sought various means to obtain quality services. One method of VoIP that helps save costs without compromising quality is the Mobile SIP Trunk solution.

The keyword “Mobile SIP Trunk” has seen increased searches recently, particularly since CGVtelecom officially launched its Mobile SIP Trunk service (MOBILE NUMBER SOLUTION VIA IP).

SIP Trunk is a service using VoIP to facilitate the connection of branch offices to the Internet. With this service, the Internet replaces traditional telephone lines and allows users to communicate with both fixed and mobile phone numbers worldwide.

SIP Trunk combines SIP (Session Initiation Protocol) with Trunking to create a term referring to phone systems where a large number of users share a small number of transmission lines.

Here is the translation into English:

“A ‘Trunk’ is a line or link capable of carrying multiple signals simultaneously, connecting large switching centers or nodes within a communication system. Trunking also provides network access to multiple customers by sharing a set of lines and/or frequencies instead of providing them individually.

‘SIP’ stands for ‘Session Initiation Protocol.’ SIP has a wide range of applications including controlling multimedia sessions (voice and video calls over IP) and integrating telephony and internet services such as voice calls, audio and video conferencing, data transmission, and messaging. Additionally, new applications for SIP are continuously being added and developed.

Together, SIP and Trunk can combine voice and data connections into a single transmission line. When combining SIP Trunking with an internal PSTN network, companies can communicate over IP with external parties. SIP Trunking can then replace traditional PSTN fixed-line systems with an IP phone system connected through a SIP Trunking service.”
