Hi, I have an X100P which receives an analog line from another PBX. These are the relevant entries in extensions, PHONE1=Zap/1 [macro-extensions] exten => s,1,Dial(${ARG1},20) exten => s,2,Voicemail2(u${ARG2}) exten => s,102,Voicemail2(b${ARG2}) exten => s,103,Hangup [home] include=>tozap exten => 2201,1,Macro(extensions,${PHONE1},${PHONE1VM}) exten => 2202,1,Macro(extensions,${PHONE2},${PHONE2VM}) [tozap] ignorepath => 9 exten => _9XXXXXXX,1,Dial(${LINE1}/9WW${EXTEN:1},90,rt) ; is 9 and a second wait for dialing tone from the legacy PBX central, then the number. exten => _9XXXXXXX,2,Congestion I don't know why yet, but when dialing any matching string I get busy tone. if I change the stanza to: exten => 9,1,Dial(${LINE1}/9) I get the X100P dialing 9 but it takes a long time, up to 4 or 5 seconds. zaptel and zapata are fine, signaling is fxsks zttool says everything is fine, usb and all unused devices are off from bios. Thank you in advance.
