1. A method of managing device connections in a first telecommunications network, the method comprising:
receiving a handover connection request from a wireless device via a second telecommunications network;
requesting an allowlist from a database associated with the first telecommunications network;
determining, based on a content of the handover connection request and the allowlist, whether the wireless device is capable of performing an enhanced 911 (E-911) technique associated with the first telecommunications network;
comparing a Type Allocation Code (TAC) for the wireless device to the allowlist;
in response to a determination that the TAC is not present in the allowlist, determining that the wireless device is not capable of performing the E-911 technique; and
in response to a determination that the wireless device is not capable of performing the E-911 technique, performing a denial operation with regard to the wireless device.
