VoIP Phones - Zyxel VMG/DX Routers: Difference between revisions
The instructions should work for any Zyxel router on the Opal firmware platform.
NOTE: There is a bug in some firmware versions of
For each inbound call the delay will increase until the router is power cycled.<br />
Zyxel are aware of this as of 2023-10-23.<br />
Workaround: Set the region to USA or NOR (the ring style you hear will change for inbound and outbound calls! The ring people calling you will hear does not change). Or reboot the router regularly to keep the delay low.<br />
Fix: Firmware "V5.70(ACDZ.2)C0_20231201" and newer do not suffer from this problem.
