Q.931 Parser and Call recording software for ISDN/T1

Now we need to develop software for that server.

Windows 2003/2008 server and processing those UDP packets received from adapter.
We need to write software (Windows service) that will
1. Process incoming UDP packets and retrieve Q.931 signalling information from D-channel
2. From Q.931 information figure out which b-channel is corrently engaged in call.
3. Retreive data from B-channels and record the calls in WAV format to a disk.
4. Callect/display statistical and debugging information.
T1 adapter sends 300 UDP packets per second to Server's UDP port 1024.
Every UDP packet contains 60 T1 frames for one direction. ...
