Yeah, that sounds like a really great solution.
But it has two drawbacks:
- You have to use vonage
- You need IP network access in order to get the emails
But as I said I am looking towards a solution that doesn't depend on IP
network and is mostly carrier independent.
So I think it is (at least in the beging) inescapable to setup your own
voicemail server. The server then could use many different ways to
communicate with the phone, either email or sms or direct gsm
connection. But what we need is a consistent protocol for each of this
method and not many in form of a carrier specific protocol. You do not
want to write hundreds of parsers.
So our server would you send an sms or if you have a IP network
connection an email and than would display its content nicely on the
screen with the ability to press on the entry an immediately hear your
I really like the idea of Wilhelm Chung to use sms to notify you about
missed calles and parse the date and caller out of it. My current
carrier sends me sms with only date. Well that would be start, but you
would have to write a parser for each carrier and each language used.
And even then direct access to the voicemails would be quite
complicated, because they first tell you what voicemails you have wait
and than you can choose which you want to hear.
So I think we should workout some kind of a protocol for both gsm/sms
based and ip-network/imap based access to voicemails.
And also we should constantly talk to telkos and ask them what they
think about this and where they see possibilities to implement visual
I for myself see huge potential to create visual voicemail system with
the help of the openmoko community and establish a new way to interact
with your phone not only for voicemails.
