  1. Whitelisting 3CX voicemail server

    The last 2 days, I have found my hosted email service blocking 3CX voicemail delivery. What is the best address to whitelist to avoid this from happening? This happened several years ago, was corrected by my email host and is recurring for some strange reason.

  5. Solved Whitelist doesn't prevent our IP from being blacklisted

  7. Remove WAN restrictions for whitelisted IP's

    Hi, In my experience there are various reasons you may want a device to be able to communicate with a cloud server outside of an SBC. I know there is an option to allow this per extension but it would be just a touch smoother if whitelisting an IP covered all extensions at that IP...
