I would concur that this has already been done. Look at some of the big
players on the market. I won't drop their names
But several already have this.
The biggest problem is seamless integration on the mobile handset. Each O/S
(blackberry / android / iOS / etc) allows the integration
Differently - and causes the end-user experience to be different.
For example - on Android and Blackberry some really good hooks can be made
into the Dialer / phone system - while on iOS you
Have to contend with opening an App and limitations on backgrounding etc.
Don't get me wrong - I'm a huge iOS fan boy!
The simplest approach would be a SIP client - however - again you are
dealing with more issues:
(a) user having to open an app
(b) does the provider allow SIP over their network
(c) what is the quality going to be
As far as doing it from the telco / network provider side. This is an option
*HOWEVER* it is usually reserved for serious
Players. I spoke with one vendor who was willing to do it - but only under
the right circumstances and when my name was not
That of a large hardware networking equipment designer - I was blown off.
If you'd like more information - you can contact me off-list -- I've ran in
these circles and seen what can / can't be done.
It's not new - it's more a matter of what market you are looking at - what
devices - etc.

A typical approach is a client on the mobile phone which sends all
outgoing calls first to the user's PBX and then uses 2stagedialing to
dial the real target. Thus, the PBX always knows the status of the
For incoming calls which terminate directly on the mobile phone
(withouth beeing routed via the PBX) the client can use data services to
signal the device state to the PBX.
Without a client software on the mobile phone there is no way to get the
mobile's presence - except the mobile operator gives you access via
dedicated APIs (which some do)

Isn't that a feature supported the mobile "VPNs"?

I guess you need a dedicated client to signal the call ringing on

I think all mobile phones support address book syncronisation

normal "VPN" feature, or use a client on the mobile phone which maps the
shortkey to the full length number

Just configure the voicemail extension of the PBX as voicemail number in
the mobile phone

I think pickup can only work if the call is routed via the PBX - then
the PBX can do the rerouting of the call to the mobile which picked up

Just install a proper SIP client on the mobile phone ;-)

Sure - seamless mobile integration into PBX is a hot topic currently...
