SIP (Session Initiation Protocol)
Reducing voice communication costs while also providing enhanced services
SIP Explained
One of our Collaboration and Contact Centre experts, Nick Osborn, explains a little about SIP.
A scalable and resilient solution
SIP (short for Session Initiation Protocol) is in no way new – it has been widely used over the last fifteen years and is the perfect technology for the delivery of telephone calls into your business, and a great replacement for slowly retiring, ISDN.
SIP is more flexible than traditional services such as ISDN or TDM, instead of being tied to a physical connection it can be delivered over the internet or a private network such as MPLS. This in turn means telephone numbers are also no longer tied to a physical location and calls to direct dial number can be delivered anywhere in the world no matter what geographic location they may reflect.
A great option as a disaster recovery solution
The flexible geographic range makes SIP a great option as a disaster recovery solution. With a range of options available like having a primary connection into your own Data Centre and secondary into a different Data Centre whether it be ours or something like Azure, an automatic fail over to a secondary location can be on hand in the event of a disaster.
Flexible and cost-effective
As a capacity-based solution, businesses can achieve cost savings by only paying for the channels they require for the number of concurrent calls they want to be able to make or take. Furthermore, because it is delivered by IP SIP can be flexed up and down to satisfy seasonal demands or planned events.
Benefits of SIP
Cost efficient and easily scalable up and down as needed
Disaster recovery – numbers can be redirected easily including individual diverts to mobile numbers
Ultimate agility – once using SIP numbers can be moved around easily
