This can be achieved through DSCP marking (46) or a guaranteed 100 kbps per device. Implement QoS to prioritize traffic, targeting everything sent from the phones to the Cytracom system using the above IP range.This is necessary to avoid issues with BLF and MWI. Increase the UDP timeout to a minimum of 180 seconds for global and firewall rules relating to Cytracom services.FTP (if call recording is used and uploaded to a locally or cloud-hosted storage solution): IP: 18.211.94.44.Firmware: IP: 54.227.140.71, FQDN: fw. or The SIP ALG is disabled by default and we recommend that it remain disabled until the bug is fixed.In this example the name VANTACTSNAT is given to the SNAT Policy.
