Hi Ashwin,

I'm going to jump in and answer that one.  

You have two broad options for mobile network integration, depending on how 
tightly coupled you want the integration to be and what capabilities your 
existing network has.
- Option A is to use call forwarding - you can establish trunks between the MSC 
and the IMS, and use application servers to define call twinning callflows if 
you want to twin your Clearwater based line with your mobile line.
- Option B is to use IN integration (typically WIN in CDMA networks) - for this 
you need an IN application server on the 3G network that will intercept calls 
sent and/or received on the 3G network, and redirect those calls to the IMS 
network (or vice versa).  

What exactly are you trying to achieve?

Thanks,
-Donny
