Customer location function – Telsis: ocean services platform (OSP)

In most cases, the SIP protocol is now used to initiate and terminate VoIP calls. SIP registration on the network operator’s VoIP platform is required to make calls via connections of this type. To register the SIP account on the other hand, account data is required, which is usually configured on the customer’s router. If this account data gets into the wrong hands, criminals could take the data to register via any internet connection and use the telephone line for unlawful purposes. If this happens, customers can no longer make calls on their lines and might have to foot the bill for fraudulent activity on their SIP account.
There are lots of ways that criminals can get hold of account data. For example, your line can be hacked and account data stolen, or data isn’t deleted when the router’s sold.
To ensure that SIP account users are the lawful owners of the internet connection and therefore the relevant SIP account, any attempt to register must entail a check on whether the SIP account is also registered via the associated internet connection.
Telsis has developed the new CLF (customer location function) for its multifunctional OSP IN platform to perform this task. Any time an attempt to register an SIP account is made, the CLF automatically checks on a database whether the internet connection and SIP account match. The network operator provides a database that combines an internet connection’s current IP address with the phone number of the SIP account belonging to the internet connection and creates a data set. If anyone tries to register, the phone number and the IP address of the SIP to be registered are now compared with the data in the database. The registration is only forwarded to the registrar and the account registered once this comparison tallies. Otherwise, registration is rejected.
