That's one way. But we can always SPAN the gateway. I also got to know that using MTP (Media Termination Point), the calls made or received through SNR can be recorded.
The approach I am thinking should work:
When it's an incoming call: PSTN call comes to V.G.-> The deskphone and the SNR associated Mobile Phone rings- user receives the call on mobile- the deskphone and V.G is still in loop- SPAN the gateway and get the RTP.
When it's an outgoing call: User dials using SNR associated mobile- call lands to enterprise number on CM- CM dials out to PSTN via. V.G- SPAN the gateway and get the RTP.
