Today the new model of “trunking” to IP-enabled enterprises can result in lower telephony costs and a rapid Return On Investment (ROI) plus the opportunity for enhanced communications within the enterprise as well as with vendors, customers and partners.
The possibility for a rapid return on investment is a key driver of SIP trunk deployments.
SIP trunking delivers the following benefits:- Eliminates costly BRIs (Basic Rate Interfaces) and PRIs (Primary Rate Interfaces) services
- Removes the need to invest in additional PSTN gateway capacity as you grow
- Reduces capital expenditures: edge devices offer a lower investment path in adding new lines as they are typically cheaper per line than the corresponding PSTN gateway
- Optimizes bandwidth utilization by delivering both data and voice via the same connection
- Maximizes flexibility in dimensioning and usage of lines as you avoid having to buy capacity in chunks of 23 (T1) or 30 (E1) lines
- Provides flexible termination of calls to preferred providers; calls to anywhere worldwide can be made for the cost of a local call
- Enables redundancy with multiple service providers and links
