1. A method, comprising:
receiving session initiation protocol (SIP) messages from user equipment devices (UEs) via wireless uplink connections;
monitoring a rate of the SIP messages received from the UEs;
identifying that the rate of received SIP messages exceeds a first threshold during a first period of time, wherein the first threshold corresponds to a congestion condition; and
reducing congestion on the wireless uplink connections by sending SIP response messages to instruct the UEs to resend the SIP messages using time delays that vary between different UEs.
