Hello,

I would like to ask if there are any possibilities how to monitor voice call, especially the error cases, when the call crashes, cannot be dialed etc., in the public SDK CTelephony class are only methods for monitoring the call state (connecting, disconnecting,...), network registration state and signal strength, but I would like to get from ETel more information related to the Um interface protocols - like get more information about network layer ( CM/RM/RMM ) or even about the LAPDm.

I guess this is possible only with non-public API possibly granted by Nokia.
Anyhow - does anybody experience with monitoring the call state on lower level? Any hints are welcomed.

The reason for this is making voice call monitoring application.

Thanks a lot
Regards,
