Try putting a 1 second wait as step 1 in the dialplan, the SIP invite is probably being send before the display IE arrives. The display IE is used for CNAM delivery, and should not exceed 15 characters.
It is very common to put a message in the display IE that indicates that the CNAM info will be sent in a subsequent Facility IE, and for that you must wait 1 second. If the ISDN setup actually contains information in the display IE, and that is not being captured as the CNAM (callerid(name)) you might need to capture he ISDN messaging to debug it, the telco can usually provide such a trace. I would bet that the display IE contains a information following message, and what you really want is in the facility IE that follows. Very common, as is the Wait(1) workaround. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Oscar Patricio Sent: Wednesday, July 25, 2007 6:55 AM To: asterisk-users@lists.digium.com Subject: [asterisk-users] Display IE Hi! I have an Asterisk Box that has 2 E1 connections: one to the PSTN and one to a PBX. It is acting as a telephony gateway. I have a problem: the PSTN sends information in the Display IE (in setup, information , etc.messages) that the PBX needs por internal processing. The asterisk does not relay the ISDN frames coming from the PSTN. It regenerates them, and when it does, it ommits the Display IE. Is there a way that i can force the asterisk, not to ignore this IE in the ISDN messages? If anyone can shed some light on this issue, i would be very grateful.
