FBlack_111:

Network level intercept messages are free as they're streamed through the signalling path (just like ringing). Once the MVNO replaces the default intercept and routes the call to an application such as the missed call SMS, the call becomes chargeable and the caller get billed.

My point is that the new dual IMSI package could have been setup just like the single IMSI packages and routed to network default intercepts.

In my case I route all my incoming calls via an IP PBX and never give out the actual DIDs associate with a SIM. Having to pay for each and every call I miss can add up pretty quick. On top of all this I also can't take advantage of the calling number detection in the SMS intercept as the current PBX firmware doesn't properly handle RPID (remote party ID) for my outbound trunk(s).
