Hi Davide!<br>
<br>
Probably there are several ways to implement that - e.g. (A) really terminating the call on one ISDN port and then create a new call on the other port (e.g. using Asterisk) or implement (B) a "tap" that just forwards everything and sniffs the data.<br>
<br>
option (A) should be possible - just configure Asterisk to accept the call on port 1 and dial out again via port 2.<br>
<br>
The received useruserinfo is put into the channel variable "USERUSERINFO". The same variable is used to set on the outgoing channel.<br>
<br>
Therefore I guess you need to use something like that in extensions.conf:<br>
<br>
[fromPort1]<br>
; copy user-user info into a global variable so that the<br>
; variable is also available on the outgoing channel<br>
exten => _X.,1,Set(_USERUSERINFO=${USERUSERINFO})<br>
; trunk group 2 is allocated to ISDN port 2<br>
exten => _X.,n,Dial(DAHDI/g2/${EXTEN})<br>
<br>
<br>
regards<br>
Klaus<br>

Hi All,<br>
<br>
I'm not so skilled in Asterisk/ISDN.<br>
<br>
I need to manage an OpenVoxB400E in a Linux/Asterisk environment in<br>
order to:<br>
<br>
1) intercept input traffic from an ISDN phone directly connected to one<br>
NT cofigured port of B400E<br>
2) sniff some infos from D channel: expecially UUI (User to User<br>
Information)<br>
3) forward the call to one output TE configured port of B400E (on demand<br>
overlapping a tone or silencing B1/B2 channels)<br>
<br>
I need not to introduce echo and keep the D channel unaltered<br>
(expecially UUI must pass from input to otuput ISDN port without any<br>
modifications).<br>
<br>
