With the greatest of respect, I should like to float a thought at those who say visual voicemail is a ‘carrier service’ and suggesting it is only they who should be held to account for VMM issues.
I completely agree that mobile service providers’ voicemail systems are an essential part of the voicemail process.
However, I find it hard to accept that they (the service providers) are solely accountable for VMM issues.
The service providers’ Voicemail systems obviously needs to interface with the iOS operating system
IOS in turn, needs coding in order to satisfy the necessary 2-way interface.
It is, in my view possible that this coding is not working 100% effectively, so we should not exclude any responsibility from Apple/IOS in the unreliable process.
Over the years, my VVM has gone through phases of working perfectly to intermittent (current). It seems the transition MAY be triggered by IOS updates; possibly coinciding with upgrading iPhones.
I can think of no reason why service providers should regularly change the operation of their voicemail systems, arguably very reliable and long established as they are.
Finally, I think that mobile service providers and Apple should have coordinating sessions (assuming they do not now) so any problems of this kind can be worked on jointly, rather than the ‘blame game’. Thus their clients do not have to tolerate unreliable voicemail.
