Are you wondering why sometimes a VoIP number rings when using the – DataTools.Verify.PhoneNumber.ReachTel.VerifyPhoneNumberIsConnected method?

Where possible our 3rd Party Provider always tries to establish the connection status through the various carriers, however under their agreement that they have with their primary carrier (Telstra Wholesale), in the event that the query is congesting their network they place a short call to the handset to test the line directly. This is most common with VoIP handsets or large PBX phone systems.

To ensure compliance with the Telecommunications and Research Industry Act 2007, they ensure that landline validation is only conducted between the hours of:

Monday to Friday: 8am – 8pm
Saturday / Sunday: 10am – 5pm
