Hi, I am currently integrating our company's Toshiba PBX with the Asterisk version 1.2.1. I bought Quad T1 card, and making the port 1 to connect to PSTN PRI (use "pri_cpe" in zaptel.conf") and making the port 3 to connect to Toshiba PBX (using "pri_net" in zaptel.conf). The first stage goal is to just adding the Asterisk relay between PSTN and Toshiba system. The issue I am facing is that I can make a outgoging call from Toshiba system phones to outside; but incoming calls always fail. I can observer the call come from span 1 and routes to span 3, but the call immediatedly hangup. Did anyone have experience on this issue. I try to make use the setting of "misdn.conf" to try to print out the signalling info, but it seems that there is no logging output. Is " misdn.conf" useful in 1.2.1 version. best regards Charles -------------- next part -------------- An HTML attachment was scrubbed...
