I have just updated from 18 - 20 and my Twillio trunks just do not seem to be able to connect to the 3CX Phone System.
I am getting 2 errors from the Twillio Error logs
11200 - HTTP retrieval failure
32011 - Error communicating with your SIP communications infrastructure
I have placed all the Twillio IP Addresses in Whitelist
I have updated the IP Access Control Lists & Credentials to reflect the new Admin Username & Password
But the calls just do not seem to be able to reach the PBX - The Sip trunks are showing green in the PBX
Please Help -
