Sip trunk vs Analog telephony



SIP trunks and the upgrade to new IP telephony systems are inevitable in the near future. Large telecommunications and internet service providers are migrating their clients from the old analog or traditional telephony to the new IP telephony. Sip trunks or virtual telephone lines, unlike the old PSTN or old telephony that was delivered in physical wiring, offer a more comprehensive, modern service, with economic advantages, and also have greater flexibility at the time of contracting.

 

What are SIP trunks?

 

Sip trunks are really telephone lines that work through the internet using the SIP protocol. It is an IP telephony service that is linked with public telephony to provide one or more voice channels in a bidirectional way (incoming and outgoing calls) therefore they can be associated with DID virtual numbers and can also be connected to virtual pbx, physical telephone exchanges or plants and call centers.

 

What is a SIP trunk used for?

 

Sip trunks are used to allow the link or virtual connection between a telephone phone system, belonging to a company or user, and the telephone network of a Voip or Ip telephone provider, through the Internet. Sip trunks offer incoming and outgoing calls within their main functions, and today they allow linking landlines and mobile numbers (DIDs) to receive calls depending on the coverage of each country.
