Topic Why SIP trunking service is a perfect solution for enterprise ?
SIP service is a perfect solution for enterprise customers who already have an existing phone system and high-speed Internet because it eliminates the need for costly T-1s and PRIs. SIP is also ideal for high-volume call centers or multi-location customers because it allows you to share unused call capacity, and as a result, eliminating the need for a dedicated connection at each site. SIP trunks
also afford guaranteed network redundancy and provide failovers if case of outage.
If you are happy with your SIP termination provider, you can choose a voice only plan.
Many SIP trunking providers offer both a metered (pay-per-minute) and an unlimited calling plan. You can also choose to combine your Internet and local and long distance on a single dynamic circuit called a Dynamic PRI (another form of SIP trunking). Bandwidth is based on call volume or Internet usage ensuring optimal use of available bandwidth at all times. When voice lines are not in use, bandwidth is available for Internet access and data application.
