1. A computer-implemented method in a telecommunications network, the method comprising:
receiving, by a network server, a request from a user equipment having multiple communication interfaces to test call quality of a first wireless communication interface of the user equipment
wherein the user equipment is one of a plurality of user equipment located in a geographical area;
obtaining, by the network server in response to the request, an audio sample from the user equipment via the first wireless communication interface;
determining, by the network server, a quality metric of the first wireless communication interface in part based on the received audio sample;
tracking quality metrics associated with remaining of the plurality of user equipment located in the geographical area; and
in response to determining that a service interruption exists in the geographical area based on the quality metric of the first wireless communication interface and the quality metrics associated with the remaining of the plurality of user equipment located in the geographical area, transmitting a message to the user equipment,
wherein the message comprises at least one recommendation that the user equipment be switched from the first wireless communication interface to a second wireless communication interface in the multiple wireless communication interfaces on the user equipment, and
wherein the second wireless communication interface is different from the first wireless communication interface.
