Non-transitory computer-readable media having computer-executable instructions embodied thereon that, when executed, perform a method to identify public safety answering platform (PSAP) mid-call capabilities for emergency services calls, the method comprising: selecting a cell sector maintained by a network provider; generating a first test emergency services call identifying at least one media format or codec; transmitting the first test emergency services call to a PSAP; establishing a communication session with the PSAP; during the communication session with the PSAP, initiating one or more mid-call services signals that modify the media format or codec for the session established in response to the first test emergency services call; and receiving one or more responses from the PSAP that indicates whether the PSAP supports the media format identified in the test emergency services call and whether the PSAP supports the mid-call renegotiation to the media format or media codec in the one or more mid-call services signals.
