VoIP phone service (also known as SIP Trunk service) offers companies a better way to make and receive phone calls. On average, SIP Trunk service saves between 40-60% on phone bill costs when compared to landline phone service.  SIP service provides unlimited, nationwide calling (including Canada and Puerto Rico) for less than $30 per line per month.  Additionally, SIP provides you with call reporting tools so you’ll always know how many phone lines your business actually needs so you are never overpaying. SIP Trunking is also more flexible than traditional landline or PRI service, with the ability to increase or decrease Direct Dial Numbers and phone lines in seconds as your business evolves.  SIP Trunks connect to the cloud, enabling access to disaster recovery features that are not available with landline or PRI services.
