This module may be used for special applications that require
|
|
cross connecting of bchannels, conferencing, dtmf decoding,
|
|
echo cancellation, 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
|
|
provided in the source code.
