I have a script that I run every 30–45 days to update company and user-level call rules with additional phone numbers gathered from our CRM. When I went to run the update yesterday, I started receiving the following error on the v1 answering rules endpoint:
This API is not available with enabled feature [NewCallHandlingAndForwarding].
This led me to discover the new v2 endpoint described here:
https://developers.ringcentral.com/guide/voice/call-routing/user-call-handling/migration-guide
I don’t recall receiving any communication about this change, so it caught me off guard.
These changes also seem to coincide with a drastic shift in our phone system’s behavior regarding custom rules that began on 11/05/25, which I’m assuming is when our account was upgraded to the “new user call handling features.”
Before realizing our account had been upgraded, I spent over two hours on the phone with general support trying to troubleshoot the issue. During that call, I was told that how our phone system previously worked was “not true,” even though I have detailed custom reporting that clearly shows it was.
All that said — is there anyone I can contact who actually understands what changes were made and can help me get our phone system functioning as it did before the upgrade? General support and a developer ticket have both gotten me nowhere so far.
