Hi all, I use Asterisk with CAPI on FreeBSD 7 and Nagios only for sending and (later) receiving SMS alerts over ISDN to and from mobile users. Receiving SMS is an option to acknowledge or delegate alerts. Now I have stumbled across three issues. 1. Sharing Asterisk on the same NT with an existing PBX: We have an ISDN line with 4 NTs (8 BRI channels) and 100 telephone numbers for DDI. The protocol is point-to-point. Since connecting Asterisk behind the existing PBX is not possible, I share one of the NTs with the existing PBX. I assume that the existing PBX listens to all DDI Numbers. How can I configure Asterisk to listen to one number without interfering with the other PBX? 2. I am still confused as to how I should setup capi.conf and extensions.conf correctly for an ISDN line with DDIs! All documentation I have found (readmes and Google) mainly focuses on ISDN with point-to-multipoint (msn). Although my configuration works, I see strange behavior. After running Asterisk for about 15 minutes, the /var/log/messages log file and the console fill up about five times every second with the following message: i4b-L2 dss1_pipe_data_req: unit=0, pipe=0, i_queue full or no fifo translator!! I can stop this message using '/usr/local/etc/rc.d/asterisk stop'. You can see my configuration files further down in this mail. Do I have to set more parameters in my configuration, or should I replace my (passive) ISDN interface with an active one? 3. Sending SMS, the command above runs successfully, and I receive a message on the mobile phone. However, it displays the wrong ?Calling Line Identification (CLIP)?: It shows the main number instead of the DDI extension. smsq --motx-channel=?CAPI/ISDN1/0622100000' 079xxx8690 'Hello World?
