SBC IP Whitelist Validation Failing for BYOC Trunk Config

Hey everyone, I’ve run into a really strange issue with the POST /api/v2/telephony/providers/edges endpoint when trying to update the SBC IP whitelist for our APAC trunks. The request returns a 400 Bad Request with “Invalid IP address format” even though the IPs are standard IPv4 and match the regex in the docs. This is blocking our compliance audit for the Singapore region.
