All, I have a VoiceTronix OpenLine4 FXO card. I am running SuSE 8.2 w/ Linux 2.4.20 kernel. The Asterisk and OpenLine4 are all setup properly. I am able to dial out from a SIP phone via the OpenLine4 FXO port just fine and the quality is pretty good. However, the inbound calls from PSTN on the FXO port will not be picked up by Asterisk at all. Before loading the VPB driver, I properly configured the tone detector by using the following: export VPB_TONE0=DIAL,C,425,100,1000 export VPB_TONE1=RINGBACK,P,425,100,1000,4000 export VPB_TONE2=BUSY,P,425,100,360,360 insmod vpb In the vpb.conf file, I have: ; For OpenLine4 cards context = pstn-inbound mode = fxo group = 1 channel = 1 channel = 2 In the extensions.conf, I have: [pstn-inbound] exten => s,1,Wait,1 exten => s,2,Answer exten => s,3,Background(demo-congrats) exten => 9,1,Hangup Could anyone give me some hints on configuring VoiceTronix OpenLine4 with Asterisk? Thanks! zxu __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
