Do all the carriers I work with need to install the solution?

No. The solution works end-to-end, and only originating and terminating operators participate in the validation.

So the system will not validate 100% of my traffic?

From Day 1 the system will validate 100% of your international traffic exchanged with community members. We use a pay-as-you-go model – you do not pay for the traffic that is not validated. Typically, AB Handshake will initially work in parallel with solutions that you already use, detecting fraudulent cases which can’t be recognized by standalone tools.

We are also creating local clusters for validation based on customer requests.

Does the system work with MNP?

Yes, the validation logic takes the MNP into account. The exact implementation is largely dependent on specific restrictions and regulatory requirements, so please get in touch to discuss the most relevant option.

Does the system take into account the roaming status of the subscriber?

Yes, the validation logic takes the roaming status of the subscriber into account. The exact implementation is largely dependent on specific restrictions and regulatory requirements, so please get in touch to discuss the most relevant option.

Will there be a delay in the call setup after integration of the Call Registry?

There is no delay. Call setup and call validation processes run independently via different channels.

Does the service comply with privacy rules like GDPR?

During typical calls you send A and B numbers in SIP headers, which are open text now. Every operator in the chain has access to this data. In our case, the Originating and Terminating Call Registries communicate only with each other through an encrypted channel. There is no access for any third party. We do not transmit anything other than what you are already transmitting through signaling.

In addition, Recital 47 of the EU GDPR specifically states that “The processing of personal data strictly necessary for the purposes of preventing fraud also constitutes a legitimate interest of the data controller concerned.”
