Welcome to the Zahau case, Seattle1!
Thanks for this info. I am aware of features in many phones/services wherein you can disable Voicemail (VM) notifications on the phone itself. However, I find it hard to believe that a service provider would allow you to do "VM to VM" without having the service provider actually connect the calls and thus, tracking the VM call in the phone bill.
I understand about not charging in-plan customers a fee because both customers are considered "in-house" for using the same service provider such as Verizon to Verizon callers or AT&T to AT&T customers, but I believe the actual records of the VM/calls made would still be automatically logged by the service provider.
This is why it is odd that Rebecca's phone records indicated NO calls from Jonah on Tues ~11:30pm on 7/12/2011 or for that matter, strangely, no calls from Jonah to Rebecca anytime thereafter, not even when Adam *texted* Jonah on Wed 7am 7/13/2011 that Rebecca "had hung herself"...
As is, we have only Jonah's word that he made the phone call/VM on Tues around midnight, and of course, if the VM was actually made by Jonah, then SDLE should have Jonah's phone records to prove that. Unfortunately, SDLE has, once again, provided NO PROOF to their so-called "scientific", "iron-clad" conclusions about events such as this "suicide trigger" voicemail from Jonah to Rebecca by showing us Jonah's actual phone record for that specific date/time, or Dina's "solid alibi" at the hospital sitting vigil to her one and only son by showing us the hospital surveillance video. However, SDLE has chosen not to do so. One can only infer from this that either SDLE has no such physical evidence in their possession or they're going out of their way to frustrate the Zahaus and the public.
