To allow devices and applications to access Aircall smoothly and securely, media IPs and ports of services may need to be whitelisted in specific settings of your network to prioritise voice traffic and comply with security practices.
Please adjust the IP addresses and port range of your network infrastructure today to keep Aircall running smoothly. Failure to do so may result in one-way audio and dropped calls. It is recommended to keep old IP and port ranges during the transition.
