Systems and methods for terminating telephony communications to mobile telephony devices

A system having a memory and one or more processors and for initiating call forwarding termination procedures, comprising:

• a triggering unit that, via the one or more processors, determines that it is desirable to implement call forwarding termination procedures which result in a mobile telephony service provider that provides a telephony device with its native telephony service forwarding telephony communications directed to a native telephone number of the telephony device to a forwarding access telephone number;
• and
• a forwarding termination instruction unit that, via the one or more processors, notifies an IP telephony system that call forwarding termination procedures should be implemented, receives from the IP telephony system, an indication that the IP telephony system is unable to cause the native telephony service provider to implement a forwarding feature, and sends a communication to the native telephony service provider that instructs the native telephony service provider to implement the forwarding feature.
