16 v5 appears to not work with BT HSIPT trunk

[sifi999]

Hi All

Just a heads up we upgraded to 16.5 at the weekend and our BT HSIPT trunk has been dropping ever since and wouldn't connect. We restored a virtual machine snapshot from immediately prior to the install and the trunk is registered. Some sort of bug but if you are running the trunk then I would suggest putting off the upgrade.

Kind regards

Simon

There is an article about other sip trunks not registering and some people have resolved this by changing all the 3cx services to delayed start.

Some have said it did work some are saying it hasnt.

Maybe worth a try
