Disabling symmetric RTP for SIPREC

Twilio will disable symmetric RTP for SIPREC connections on June 30, 2025. 

Through leveraging the SIPREC Resource or <Siprec> TwiML instructions, customers can stream the audio of a call to one of Twilio’s available SIPREC partners. In the case of SIRPEC, Twilio is not expecting any RTP from the SIPREC partner or customer as SIPREC is a one-way audio stream to the customer; therefore, Twilio will disable symmetric RTP for SIPREC connections.
