Prior to moving from traditional telephone service to SIP trunking, several points must be considered.
How many people are on the phone at the same time during your busiest hours?
This will determine how many SIP channels you will need. With SIP trunking, you may purchase additional channels and as call volumes change or for seasonal businesses, reduce the number of channels (contract permitting). Some providers allow for traffic bursting in order to accommodate the occasional spike in calls without affecting the cost structure, within certain parameters.
Is Your Data Network Ready for SIP Trunking?
Network considerations that must be examined including available bandwidth, Quality of Service (QoS), and firewalls. Upgrading your Internet connection or adding a second connection may be necessary to ensure a positive outcome.
Quality of Service (QoS):
Quality of Service (QoS) prioritizes voice traffic and ensures that phone calls are getting the necessary bandwidth, regardless of data traffic on the network. Most business grade routers will provide QoS features.
A firewall provides security both within a local area network (LAN) and wide area network (WAN). firewalls are a critical component to the business network but they must be properly configured in order to work well with SIP trunking.
