<p class=MsoNormal>Hi!<br>
<br>
Thank you all for the info!<br>
<br>
But I think I haven't explained my scenario well enough. <br>
<br>
I am not relaying the calls to SIP.<br>
<br>
What happens is the following (the scenario is: a call started from an ISDN E1
PBX, through the asterisk, to the PSTN, and was answered by the remote party):<br>
<br>
1. A CONNECT comes from the PSTN containing a Display IE (which has info sent
by the telco that is used for billing purposes by the PBX) into span 1 of the
asterisk. (The telco is emulating an old billing procedure based on an impulse
count. This was commonly used in analog lines.)<br>
<br>
2. The asterisk relays the call to span 2 (which is connected to the PBX).<br>
<br>
3. The CONNECT that is sent from span 2 to the PBX does not have the Display
IE. The asterisk strips this IE from the CONNECT message.<br>
<br>
<br>
This is my problem. Is there a way that i can force the asterisk not to strip
the Display IE?<br>
<br>
Thanks and best regards to all,<br>
<br>
