SIP is a “protocol” you can use for VoIP communications and provides a way to convert voice signals into data that can be decoded by devices used by a caller. SIP stands for Session Initiation Protocol, and is essentially a way to make and end connections for data and voice transfers over the internet.
Wholesale SIP trunks can be purchased from a SIP provider in bulk at lower rates that reflect the number of SIP Trunks purchased.
Traditionally “trunks” refer to groups of cables that would link local telephone exchanges. With the internet, this process became virtual. A SIP trunk is now a collection of assigned “SIP channels”, each one of which can handle a set number of simultaneous calls. The number of SIP channels you’ll need as a business is tied to the number of simultaneous calls you’ll be making and receiving. A good SIP provider, such as SIP Trunking Services, can help you calculate this.
SIP Trunking Services is a SIP provider backed up by a team of engineers with years of expereience, so dealers looking for SIP services can relax knowing they are in the hands of SIP trunk experts. We sell wholesale SIP trunks so dealers can also be sure they are getting the best SIP trunk prices.
