SIP trunks can be easily added and removed to cater for seasonal fluctuations. How many you need directly reflects your call requirements.
The number of SIP trunks you will be assessed based on your current usage and will depend on the number of users you expect to have on the telephone at any one time. For example, if you are a business of 50 but only expect a maximum of half of the staff to be on the phone at any one time you would require approximately 25 SIP trunks.
There is no minimum and the maximum will only be restricted by the bandwidth available to you. Multiple connections and Ethernet circuits can be used to increase bandwidth.
You can easily transfer your existing telephone numbers to SIP Trunks, without loss of service. Contact our team for more information.
