1. A method, comprising:

  • intercepting, by executing an instruction with a processor outside a core mobile communications network and not included in a packet data network, packets transmitted from a mobile communication device over a radio access network towards the core mobile communications network and the packet data network, the packets intercepted at an output of the radio access network;

    detecting, by executing an instruction with the processor outside the core mobile communications network, voice over internet protocol packets within the intercepted packets;

    storing the detected voice over internet protocol packets for analysis;

    comparing, by executing an instruction with the processor outside the core mobile communications network, the detected voice over internet protocol packets with a pattern;

    determining, by executing an instruction with the processor outside the core mobile communications network, whether the detected voice over internet protocol packets match the pattern based on the comparing;

    in response to determining that the detected voice over internet protocol packets match the pattern;

    converting, by executing an instruction with the processor outside the core mobile communications network, the detected voice over internet protocol packets into a multimedia message service message as a first alert indicating that the detected voice over internet protocol packets match the pattern;

    sending, by executing an instruction with the processor outside the core mobile communications network, the multimedia service message to a multimedia service message gateway; and

    converting the detected voice over internet protocol packets into a short message service message as a second alert, the second alert to be transmitted to a short message service gateway; and

    forwarding, by executing an instruction with the processor outside the core mobile communications network, the intercepted packets to the gateway of the packet data network to send the intercepted packets towards a destination identified in the voice over internet protocol packets.
