@Victor To give you a little more context, if a new call is being raised, the response timer would stop when the call is assigned to an owner as an email is being sent to the customer. This will happen only if the update is set for customer view. If the customer and owner are the same user, even if the updates are set for customer view, no emails are being sent and the response timers is not stopping. So this issue affects only tickets with this particularity. Thanks for your help.
