Hi! Thank you all for the info!
But I think I haven't explained my scenario well enough. I am not relaying the calls to SIP. 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): 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.) 2. The asterisk relays the call to span 2 (which is connected to the PBX). 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. This is my problem. Is there a way that i can force the asterisk not to strip the Display IE?
