The cause is bad programming. You can't go from an 's' to an '_X.' the way you tried.
exten =>s,1,Answer() exten =>s,n,Wait(1) exten =>s,n,Dial(DAHDI/3) exten =>s,n,Hangup Is correct (that's why it works). What is it you are trying to achieve? -----Original Message----- From: asterisk-users-boun...@lists.digium.com [mailto:asterisk-users-boun...@lists.digium.com] On Behalf Of Songtao Yu Sent: 29 September 2010 10:56 To: asterisk-users@lists.digium.com Subject: [asterisk-users] DAHDI FXO port only recognizes the "S" extension? Hi All, When I tried to write my dial plan as below for my FXO port, which connects one PSTN line: [from-pstn] exten =>s,1,Answer() exten =>s,n,Wait(1) exten =>_X.,1,Dial(DAHDI/1) exten =>_X.,n,Hangup I got the following message: Connected to Asterisk 1.6.2.13 currently running on fax (pid = 8154) Verbosity was 0 and is now 4 -- Starting simple switch on 'DAHDI/1-1' -- Executing [...@from-pstn:1] Answer("DAHDI/1-1", "") in new stack -- Executing [...@from-pstn:2] Wait("DAHDI/1-1", "1") in new stack -- Auto fallthrough, channel 'DAHDI/1-1' status is 'UNKNOWN' -- Hungup 'DAHDI/1-1' But if I changed the "_X." to "S" extension, I can get the whole thing to work well: [from-pstn] exten =>s,1,Answer() exten =>s,n,Wait(1) exten =>s,n,Dial(DAHDI/3) exten =>s,n,Hangup Would you please let me which casuses this issue?
