Things to Consider While Selecting SIP Trunk Provider

SIP Trunking is the process used to connect IP phones to traditional phones on the PSTN or Public Switched Telephone Network through a PBX or Private Branch Exchange Network. PSTN is the traditional network which is being used for decades to help people talk to each other from a distance. PBX exchanges were used by business houses to allow people in various departments of the business communicate with each other. The two exchanges were connected by PRIs or Primary Rate Interfaces so that a person from a particular business department could connect to an independent person connected to the traditional network.

Security and support

Support for scalability is also a prime factor as business houses may want to increase the number of lines at any instant or remove some lines if they have no use.

Pricing and audio
