Question

I am trying to parse some output data from and PBX and I have found something that I can’t really figure out. In the documentation it says the following

Information for type of call and feature. Eight character for ’status information 3’ with following ASCII values in hexadecimal notation.

 1. Character  Bit7 Incoming call  Bit6 Outgoing call  Bit5 Internal call  Bit4 CN call 2. Character  Bit3 Transferred call (transferring party inside)  Bit2 CN-transferred call (transferring party outside)  Bit1  Bit0 

Any ideas how to interpret this? I have no raw data at the time to match against but I still need to figure it out.

Answer 1

Eight character for ’status information 3’ with following ASCII values in hexadecimal notation.

If think this means the following.

1. You will get 8 bytes – one byte per line, I guess.
2. It is just the wrong term. They mean two hex digits per byte but call them characters.

So it is just a byte with bit flags – or more precisely a array of eight such bytes.

Bit  7  incoming 6  outgoing 5  internal 4  CN 3  transfered 2  CN transfered 1  unused? 0  unused? 

You could map this to a enum.

[BitFlags] public enum CallInformation : Byte {     Incoming     = 128,     Outgoing     =  64,     Internal     =  32,     CN           =  16     Transfered   =   8,     CNTransfered =   4,     Undefined    =   0 }
