  	  Enable support for digital audio processing capability.

  	  This module may be used for special applications that require

  	  cross connecting of bchannels, conferencing, dtmf decoding,

  	  echo cancelation, tone generation, and Blowfish encryption and

  	  decryption. It may use hardware features if available.

  	  E.g. it is required for PBX4Linux. Go to http://isdn.eversberg.eu

  	  and get more information about this module and its usage.

  	  If unsure, say 'N'.

  	  Enable support for ISDN over IP tunnel.
  
  	  It features:
  	    - dynamic IP exchange, if one or both peers have dynamic IPs
  	    - BRI (S0) and PRI (S2M) interface
  	    - layer 1 control via network keepalive frames
  	    - direct tunneling of physical interface via IP
  
  	  NOTE: This protocol is called 'Layer 1 over IP' and is not
  	  compatible with ISDNoIP (Agfeo) or TDMoIP. Protocol description is
