Direct Chat Calls Failing Yet Again

[Verity]

50% or more of my calls never get through to me. Since 2011 when i very first started it's always been the same. AW say there is no issue.

Just to give you all an update, I reported the failed calls to A/W and this was the reply; "Callers will be advised that you are not available if you do not answer your phone within 30 seconds". - This doesn't make any sense because I log into the system and sit there and wait and wait and wait and my phone doesn't even ring in the first place so that I have the option to answer the call within 30 seconds!.

Do these calls that don't actually ring, the "unanswered calls" show on your direct chat error log?
I've had problems with Direct Chat too, wish they would put some effort into upgrading it.
